Sass and Compass for Designers. This step-by-step guide will take you through the time-saving features that makes it so much easier to create cross-browser CSS.

Are you sure you want to claim this product using a token? Ben Frain April Quick links: What do I get with a Packt subscription? What do I get with an eBook? What do I get with a Video? Frequently bought together. A few levels deep works great, and for modulespecific declarations, like the example above, Sasss nesting is a big time-saver.

Jubilat, Georgia, serif; weight: Thatll compile to: Similarly, there are many properties in the text- namespace. We can use Sass nesting to save some retyping: And background- is another good example: Nesting in Sass means less typing, using indentation to reflect the selector and property formation.

Its also a concept thats easy to grasp for anyone writing CSSnot a huge mental leap. For example, within a declaration for links, we can add hover styles that override their color and border color: The ampersand inserts the parent selector, in this case a, which will compile like so: Heres another example of using the ampersand to reference the parent selector, in which different classes trigger different styles: The ampersand is also useful in inserting overrides that happen in the presence of a specific class.

For example, lets say we style paragraphs in the main section of the site, but we want a slightly different style on a specific page. We add a class to the body, and then we can use the ampersand to slip this overriding declaration into the main one: But instead of writing an entirely new declaration, weve nested it, using the ampersand to create a unique case and letting Sass reconstruct the full selector.

Again, this is time-saving stuff, while keeping related rules in one group. You can ensure important comments copyright info, attribution, notes on hacks, etc.

This is a multi-line comment that will appear in the final. Even in compressed style. This is a single-line comment. Single-line comments are removed from the. So you can say whatever you'd like here. I genuinely enjoy listening to ABBA.

In addition to hiding your questionable taste in music, singleline comments are great for documenting your SCSS for internal. Commenting can be frequent and detailed without the worry of adding extraneous bloat to the CSS output. But if I could choose only one of those features as the most helpful, itd be variables.

We repeat ourselves so often in a stylesheet. Colors, fonts, background images, widths, etc. Variables make all of that much simpler and easier to maintain. Jubilat, Georgia, serif;. Once defined, they can be invoked within declarations: With Sass variables, wholesale changes to a stylesheets repeated patterns are updated in seconds, so you dont need to hunt through the entire file.

Using variables for style guides Jina Bolton wrote a great article on how Sass variables can help with creating a style guide from a brand palette http: Says Jina: To keep our style guide relevant, it lives in our internal-only admin section on the very same application it describes. We display our color palette alongside the relevant Sass variables and since weve built the style guide into the application using the same front-end, we can use the same variables were referencing to render this palette.

When we change values to these variables, the palette updates automatically Fig 3. Rather than creating a static style guide that can become outdated and irrelevant, using Sass variables to define a brands palette means everyone can help keep the style guide up to date and maintainable. Using the style guides variables as a foundation, Jina goes on to talk about tapping into Sasss color functions to create variations within the brand palette.

For example, heres the tiny color palette for the Sasquatch Records site, using single-line comments to note each color since its not crucial to the CSS output:. Next, using the darken or lighten color function in Sass, we can generate different shades of color that will always be based on the brand palette. What about CSS variables?

One of the terrific things about Sass and CSS preprocessors in general is that it provides a testing ground for features that might join the ranks of a proposed standard. In other words, Sass can move at a quicker pace, implementing features that dont yet exist in the CSS spec. If these prove successful enough, they could be folded into the standard.

Variables are a good example of this, and are probably the most used feature of CSS preprocessors. That means native support for CSS variables is on its way. Unfortunately, at the time of this writing, the CSS variable syntax differs from that of Sass, and is not as elegant or simple to grasp. For example, here is how you define a CSS variable for the root element of the document: And here is how you would use the variable within a declaration: The proposal uses a var prefix to define the variable but a var variable-name syntax for values.

Heres hoping it eventually works out this way. Most important, with browser support limited to bleedingedge versions of WebKit, CSS variables arent usable in production anywayyet another reason to stick to Sass. Where variables let you define and reuse values throughout the stylesheet, mixins allow you to define and reuse blocks of styles. Rather than typing the same rules over and over again in various declarations, you can use mixins to define a group of styles just once and refer to it anytime those styles are needed.

To illustrate, lets create a mixin for a heading style that Im using in a few areas on the Sasquatch Records site Fig 3. While these titles may appear in various locations on the page, their CSS is identical, which is a perfect situation for a mixin. First, well define a mixin in Sass using the mixin directive at the top of the.

Sass for Web Designers by Dan Cederholm

Ill name it title-style, and Ill define the rules for margins and fonts: Once its defined, we can now refer to this mixin anywhere wed like to insert those styles by using the include directive. This will compile to: Jubilat, Georgia, serif; font-size: So, later in the stylesheet we can call the same mixin, which will compile the same rules: This lets us avoid duplicating the shared stylesor adding a class to the markup that both headings could theoretically share.

Mixins can be included with additional rules as well: Shared styles can be abstracted into mixins, and youll still have the ability to override or augment those styles with additional rules. Powerful stuff! Mixin arguments Sass mixins can also take arguments that we pass to the mixin when we call it. For example, lets add an argument for specifying a color along with our title-style mixin.

Specify arguments with variables inside parentheses when defining the mixin: When calling the mixin, we can now pass a color to it here a lovely burnt orange , along with the other rules: Multiple arguments You can pass multiple arguments by separating the values with commas in the mixin definition: And heres the mixin being called from two different selectors, passing differing arguments for color and background: Which in this case will compile to: You can start to see how flexible mixins can be.

Through arguments, consistently-shared rules can sit alongside those that differ slightly. Defining defaults for arguments When you use mixin arguments, its often convenient to define defaults. That way, you simply call the mixin with no arguments, if thats the norm, but can still pass in overrides. Even though weve defined a light gray default for the mixins background, we can pass an argument for something different: Which will again compile to: Additionally, when you have multiple, default arguments defined for a mixin, you can override those selectively without having to redefine them all.

And if we want the color to be the default blue, but we want to override the background to be pink, we only need to pass the background: While the values might differ for these properties throughout the design, so much is shared and repeated, and Sass makes dealing with CSS3 stacks an absolute breeze.

Cant remember the syntax for creating CSS gradients? Make it a mixin! We can then make anything on the page rounded by calling that mixin: Lets add this mixin to the previous div. No need to write those vendor-prefix stacks over and over. Write once, reuse whenever youd like. It differs depending on the browser, its not easy to remember, and historically the spec has evolved quite a bit, forcing authors to update their stylesheets.

For all of these reasons, Sass and specifically the mixin makes using CSS3 gradients bearable and future-proof. Should the spec change again, well only need to update the syntax once, in the mixin. To ensure the gradient works in the most browsers possible and falls back to a solid color should the browser not support CSS gradients, well need a hefty stack of properties:.

Notice each vendor-prefixed property takes the same from and to hex colors to create the gradient going from top to bottom.

Using a Sass mixin, we can make this much simpler to call by plugging in the gradients colors as variables passed to the mixin. Who can remember all of these variations each time a gradient is needed?

Lets make this easier on ourselves. Thankfully, we only have to write this monstrosity once. Now, when we want to create a simple linear gradient, we just call the mixin with two colors of our choosing and Sass does the rest. For the Sasquatch site, the declaration for the active tab style goes like this: That is not only bearable, it just makes sense!

As if its written in English.

And I can reuse this pattern, for say a blue button Fig 3. As you may know, the linear gradient were using here is one simple example, and CSS gradients are capable of much more complexity, like color stops, radial gradients, multiple directions, etc. Sass can help with those situations as well, abstracting any shared patterns into a reusable mixin.

But often these mixins are even repeated across projects. Wouldnt it be efficient to also write all of these once and reuse them for any project where youre using Sass? This is handy for a variety of reasons: Variables can be defined in their own file, then imported whenever needed, regardless of layout and other page-specific styles.

Imported SCSS files can contain project-agnostic mixins that can be shared and reused. Heres how import works in practice. I have a mixins. In that file Ive defined some common patterns Ill use in every project. Heres an example of whats inside mixins. At the top of my main stylesheet screen.

I also import a reset stylesheet thats reused in every project again saving on HTTP connections and avoiding copying and pasting the same code as well as a variables file where I keep variables for site colors, fonts, etc. That allows me to import those same variables in other stylesheetsfor example, in other pages or sections of the same project, where the style guide applieswithout also importing the rest of the layout.

When Sass compiles the screen. So, you have the benefits of a single file download, with the flexibility of multiple files that contain reusable code. The Compass framework With mixins, variable files, and import, you can build your own mighty CSS frameworks to save an immense amount of time when starting new projects.

Having complex CSS3 stacks and. Taking that organizational advantage to the next level is Compass http: Compass offers many pre-written CSS patterns, which will be updated as the properties evolve and vendor prefixes can be stripped away. Compass also makes image sprites and typographic systems easier to handle Fig 3. I always suggest creating your own frameworks, as its best to understand what is happening with your code as much as possible.

But as a learning experience, other frameworks can be incredibly beneficialthey let you see how others set up projects and increase their efficiency. And Compass is no exception.

A little Googling will unearth many helpful Sassers sharing their mixins on GitHub or their own sites. Chances are, that. CSS3 stack that looks ugly and unmaintainable already has a mixin written for it, so take advantage of the community! Heres an example. You have an alert message style with two options at the top of the page.

One style handles standard alerts Fig 3. These styles are almost identical, save for the background color. Typically, we might create a base class for normal alerts and then a second class that overrides the background color only. Instead of littering the markup with extra classes to handle those small exceptions, we can use Sasss extend function to chain together styles that are shared amongst multiple selectors. Additionally, we can then add extra overriding rules to make a new unique style without duplicating the shared styles.

So if we wanted to use extend to handle the two types of alert messages, we could simplify the markup to just one class: Then use extend to include the styles from the h2.

Sass will then efficiently compile the extended class like this: Now, sure, we couldve written our CSS this way from the beginning, but the extend syntax makes it fasternot to mention its clearer which styles are shared between classes.

Its far easier to wrap your head around whats happening. Using extend also allows us to be terser in our semantics, defining class names based on meaning rather than appearance. Multiple extends You can also extend multiple classes within a declaration, which chains together all the styles from each class: Again, Sass efficiently organizes things, grouping the shared styles together using comma-separated selectors and then creating single declarations for any exceptions.

Using placeholder selectors with extend What if the class youre extending exists solely for the purpose of extending other styles?

In other words, you might create a class thats not used on its own. Enter placeholder selectors, which allow you to define phantom classes that wont appear in the outputted CSS on their own. You can reference placeholders using extend. Lets take a look at this in practice. Well create a class for a block of styles that define a button.

The awards of design, creativity and innovation on the internet

We can call this rule set in other classes as we did previously, using extend. Placeholder selectors are especially helpful in creating blocks of styles for design patterns that may or may not be used in frameworks, style guides, or starter templates, for example , since unused placeholder classes wont litter the compiled stylesheet.

Its good to keep that difference in mind when youre debating which to use. For example, overuse of a mixin can result in a bloated CSS file in which the contents of the mixin are present in the compiled CSS every time its called in Sass. If you find yourself using a mixin over and over throughout the stylesheet, keep in mind how that will compile, and consider whether it makes sense to use extend or turn those repeated styles into a class that gets reused in the markup instead.

Dont over extend yourself Using extend is a powerful way to share styles between classes, but be careful; when used too much, the compiled CSS starts to get a bit hairy. Extending the same class repeatedly throughout the stylesheet can result in a monster declaration.

When using Sass, its easy to forget what the compiled stylesheet will ultimately look likemake sure to keep tabs on how Sass outputs your work. You now have the power! Weve covered the basics of Sass: Sass is capable of even more, if you want to dive deeper. In the next chapter, were going to talk about how Sass can help with responsive design and media queries. Lets take the plunge. I wanted the main focus of this book to be the basics of Sass, proving that Sass doesnt have to mean ripping apart your workflow.

But in this final chapter, I do want to talk about some advanced techniques with Sass and media queries that have greatly simplified some otherwise complex CSS in my daily work.

Sass is as powerful as you want it to be. Using it for variables and a few mixins will make your life easier. But it can go beyond that if you want it to. Id like to share how Ive used Sass to build responsive, HiDPI-capable projects, and how it once again makes the heavy lifting quite manageable. The ability to listen to the browsers viewport for varying dimensions and then apply certain styles based on those dimensions is the cornerstone of creating flexible layouts that adapt to different devices.

For instance, you may want to adjust the width of a containing element should the browser be less than pixels wide, using a media query: In Sass, you can nest media queries inside the original declaration, and they will bubble up into their own separate declarations when the stylesheet is compiled. Its wonderful. The above will compile to: Nesting media queries avoids rewriting the selector section. Its also immensely convenient that the media-query declarations slot right under the original selector.

Ive found it much easier to understand whats happening to an element under varying viewports by having the media queries nearby in context, rather than gathered at the end of the stylesheet or in a separate document. Using variables to define breakpoints Media-query bubbling is a wonderful convenience that Sass brings to responsive design, but there is still quite a bit of repetition. In each declaration, were specifying the breakpoints px and px in the previous example. Often while designing, I tweak those breakpoints based on the particular design Im working on and observations on how the layout reacts,.

In other words, those breakpoints that youre specifying in each nested media query could change. Itd be great to define those once and be able to edit them in one spot. Sass variables to the rescue! Lets create some variables for three breakpoints well use in our media queries.

Im going to name them something flexible and not tied down to a specific device or finite value. With the breakpoints defined as Sass variables, we can as of Sass 3. If we later decide to tweak those breakpoints, we need only edit the variables once, and Sass will take care of updating them wherever we used them. This helps tremendously during the initial development of a responsive design, when those breakpoints are a moving target depending on the design requirements and the way the design needs to adapt.

Even math is possible here, as we can add to or subtract from the breakpoints value: Will compile to: Going a step further, you can also define an entire media query as a variable not just the numeric value: Thats a special way to alert Sass to compile something within a selector or property name.

The above SCSS will compile to:. When you nest media queries within the declarations they affect, variables save you a ton of repetition. But we can even simplify things further with content blocks, also introduced in Sass 3.

Combining content blocks and mixins By using Sasss content directive, you can pass entire blocks of styles to a mixin, and Sass will place those blocks back into the declaration that calls the mixin. That sounds confusing, but in practice its simple and handy. Lets create a responsive mixin that handles three different breakpoints, with content placeholders for whatever styles wed like to include for each breakpoint.

Well also use variables to define the small, medium, and large breakpoint widths as we did earlier in the chapter. The content placeholder allows us to further pass blocks of styles to the mixin that get inserted inside the media query.

With this single mixin set up, we can now call it from any declaration using a compact pattern that reflects the way we think about things: Sass feeds any styles to the appropriate media query and reconstructs the declaration with everything in its right place. Using content blocks for writing contextually-placed media queries makes responsive design a heck of a lot simpler with less repetition.

Its also easier to grasp how an element will be adjusted across device widthssuch as how a headings font size will vary as the width of the viewport narrows.

The entire progression is spelled out in one spot: Keep the output in mind Its important to point out that this method results in a lot of repeated media queries for each selector in the compiled CSS.

Ideally, Sass would let us nest the queries to keep the contextual connection of rules collected in one space, but then group shared media query rules when compiled.

For example:. Would compile more efficiently, with shared rules wrapped into one media query: For a large stylesheet that uses responsive design with frequent media queries for multiple viewports, this would reduce the compiled CSS file quite a bit. Unfortunately, Sass doesnt yet? So for now, thats how well roll. Apples gorgeous Retina screens, for example, squeeze twice the number of pixels compared to that of a normal display.

That means beautiful clarity and saying goodbye to fuzzy pixels! But only if you take the time to create graphics that reflect this super-sharp new world. Alternatively, there are craftier ways to handle selective image-serving via media queries and JavaScript, such as Scott Jehls brilliant Picturefill project http: For devices that support the extra pixels, well create a second version thats twice as large and reduce it to pixels in the markup for twice the clarity Fig 4.

For background images, we simply use CSS media queries in modern browsers that support them to determine whether the display is HiDPI and render the appropriately sized image. On the Sasquatch Records site, for instance, we have a little list of social network links in the sidebar. Each links icon has a background image specified in the stylesheet Fig 4.

In the Dribbble link, the CSS to align a normal-resolution icon to the left of the text might look like this: For HiDPI displays, we override the icon with one that is twice as large, and then squeeze it down to the right dimensions using the CSS3 background-size property. To detect whether the display is HiDPI, we use a media query and the min-device-pixel-ratio property in CSS3 which varies depending on the browser vendor. Essentially, were saying that if the displays pixel ratio is at least 1.

The difference, when viewed on a HiDPI display, is stunningly sharp. All those fuzzy edges disappear Fig 4. As you can imagine, retinizing your interfaces can result in a pile of repetition, referencing that media query and a second image every time youd like to override your normal-resolution background images.

Heres where Sass can make this process rather painless. We can create a Sass mixin that handles all the heavy lifting, even forming two different file names with a bit of crafty concatenation.

Heres the retinize mixin I use in my everyday projectsIll break down each important section. The first line of the mixin sets up the four arguments we need to build the right compiled code: Those four arguments are listed like so: Calling the retinize mixin is as simple as plugging in those four values anytime youd like.

For example, lets call the mixin for the Dribbble icon, a PNG that should be rendered at Back to the mixin itself, the second line forms the normalresolution background-image rule by stringing the arguments together.

Sass can concatenate! Were adding the file path to the image, then adding the file name and the period and the file type, which will compile like this: With the normal background image in place, well now add the media query that will override that image with the 2 version for devices that support a 1. Again, were including all the vendor-prefixed properties to ensure this will work across as many browsers as possible.

Next we need a way to reference whatever selector were applying this media query to, and that depends on where weve called the mixin from. In our example case, its li. Notice also that were using Sasss concatenation ability to append a -2x to the file name to refer to the larger image. Its a good idea to settle on a naming convention like thisa short bit of text that makes managing assets and calling file names in Sass easier: Normal image: But I think -2x works just fine.

The final piece of the mixin is the background-size property and its -webkit- and -moz- prefixed equivalents , which tells the browser what dimensions its going to stuff that larger image into: Mixins inside mixins!

Mixins can include other mixins. A mixinception, if you will. Dont worry, the universe wont explode! In fact, we can go a step further in DRY-ing up this code, extracting the vendorprefixed min-device-pixel-ratio rules into a variable and the background-size property stack into its own mixin.

Then these extracted parts could be reused in other sections of the stylesheet or additional mixins. The other advantage here is keeping any vendor-prefixed properties in one spot so we can edit or prune them if the specs change, or once prefixes are no longer necessary and wont that be a celebratory day.

First, lets replace the pixel-ratio portion of the media query with a reusable variable. As mentioned earlier in the chapter, a variable that appears within a selector needs special interpolation characters around it: Then well define that variable with the stack of pixelratio rules, which is also reusable elsewhere in the stylesheet if needed:.

Next, lets create a mixin for background-size that takes a width and height attribute and includes the vendor-prefixed properties as well as the real, un-prefixed one. Anytime we want to use background-size on a selector, we can now call this mixin: And there you have it. Weve refactored the original retinize mixin to include code that can be reused in additional styles or. Thatll reduce the amount of repetition throughout our Sass code, and keep shared styles in as few places as possible for future updates and maintenance.

I also hope that its dispelled some of the misunderstandings that Sass sometimes bears: You have to learn Ruby. You need to change your entire CSS process. You need to be an expert with the command line. As weve discussed, its much simpler than that. But Sass can be as powerful as you want it to be. At the least, its a fantastic tool that can fit nicely beside your systems and workflow without disturbing the CSS youve been writing for years or if youve only been writing CSS for months, well thenmonthsand bravo!

Its very similar to Sass in that it also supports variables, mixins, and other functions, but it uses a slightly. LESS also has a client-side option for compiling, which serves. Its a handy way to work locally and in development, as no command line or app needs to run the conversion for you. However, client-side compiling is not recommended for production sites. From my perspective, Sass has a more active development cycle and community behind it, and is a bit more robust in its functionality.

Youre already winning if youre using a preprocessor, regardless of which one. For a great comparison of Sass versus LESS, have a gander at Chris Coyiers thorough article, in which he breaks down the differences and pros and cons http: These debates can at times become religious warfare, but the key thing is to use what youre most comfortable with.

Both will help immensely in easing the creation of smart stylesheets. Its syntax is more like Sasss original syntax optional indenting, optional omission of braces and semicolons. I like tools that dont alter my normal workflow too much, so for that reason I havent checked out Stylus extensively.
