You will also find tips and notes all over the book to help clarify those small and simple details most books and tutorials assume you already know. The concentrator automatically bypasses disconnected stations. Single attach station SAS o Dual attach station Noreen E.

Once I realized this, I could dive in without fear. Ineicient, bloated stylesheets can be just as ineicient and bloated when using Sass. Good organization and smart thinking still apply here. But when used properly and intelligently, Sass can be such a massive assist in creating websites. Our irst task is to install it on your computering device of choice. So, before we start using Sass, we need to install Sass. Simply ire up Terminal. Installing RDoc documentation for sass At the time of this writing, the latest oicial version of Sass is 3.
Installing the latest pre-release version You can also choose to live on the bleeding edge, and install the latest alpha version by adding a pre lag at the end of the com- mand. Using the latest alpha is not only safe, but it also enables you to take advantage of the latest functionality. Fetching: sass And fear not! Essentially the command tells Sass to watch a speciied. Press Ctrl-C to stop.
If the ile is updated, Sass will convert and overwrite screen. In other words, every time you save changes in your Sass document, the CSS ile will update instantaneously. In fact, I ind it useful to separate my. Sass File Organization Figure 2. You can also tell Sass to watch an entire directory, rather than just a single stylesheet.
So using the above ile structure, I could use the following watch command to monitor changes on any of the. That said, there are desktop applications that make it even easier to manage the monitoring and output of Sass iles. Fig 2. In addition to desktop apps, some development frameworks have built-in support for Sass. Again, no command line required. It was this admittedly OCD-ish formatting control trade-of that initially turned me of and prevented me from using Sass.
That may sound ridiculous, but if the stylesheet was a product of my craftsmanship, I very much cared about how it was organized and formatted. Eventually I got over it—so much so, that I wrote this book. In the end, the formatting diferences were nitpicks. The result- ing iles are still perfectly human-readable. For those viewing source on your amazing CSS, this format will be most familiar.
Sass inserts a line break between declarations, which seems unnecessary, but aside from that nitpick, this is the style I like to use in my own projects. It closely resembles the format I use when creating stylesheets by hand without Sass which is increasingly rare!
The idea is you can easily scan the left side to ind visually grouped rules, with line breaks between. The compressed style lends itself particularly well to highly- traicked web apps, in which the performance of every ile is crucial. For a personal website this may not matter as much, and a more human-readable style might be a nicer option for those who are looking to learn from your source code. So treat the. The reason being, any changes you make to the. So stick to the. Finally, we talked about choosing an output style for your Sass-iied CSS.
The project is called Sasquatch Records—a simple website for a record label that fo- cuses on the supernatural musical stylings of mythical, elusive, beasts Fig 3.
The nesting also relects the markup structure. Do be careful when nesting, of course. We add a class to the body, and then we can use the ampersand to slip this overriding declaration into the main one: section. Again, this is time-saving stuf, while keeping related rules in one group. This is a multi-line comment that will appear in the final. Even in compressed style. Commenting can be frequent and detailed without the worry of adding extraneous bloat to the CSS output.
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. Says Jina: To keep our style guide relevant, it lives in our internal-only admin section on the very same application it describes. When we change values to these variables, the palette updates automatically Fig 3. One of the terriic 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.
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 difers from that of Sass, and is not as elegant or simple to grasp. Where variables let you deine and reuse values throughout the stylesheet, mixins allow you to deine and reuse blocks of styles. Rather than typing the same rules over and over again in various declarations, you can use mixins to deine a group of styles just once and refer to it anytime those styles are needed.
While these titles may appear in various locations on the page, their CSS is identical, which is a perfect situation for a mixin. So, later in the stylesheet we can call the same mixin, which will compile the same rules: section.
Powerful stuf! Mixin arguments Sass mixins can also take arguments that we pass to the mixin when we call it. Through arguments, consistently-shared rules can sit alongside those that difer slightly. Make it a mixin! For all of these reasons, Sass and speciically the mixin makes using CSS3 gradients bearable and future-proof.
Who can remember all of these variations each time a gradient is needed? 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. It supercharges CSS with features that make previously difficult and time-consuming tasks trivial. This book concentrates on distilling the techniques in a straightforward manner making it accessible to all, even to those that only know HTML and CSS.
