Actually, it’s really “Syntactically Awesome Stylesheets”.
For all the theme designers out there, we’ve just made your life a little bit easier. We all know that sometimes CSS stylesheets can get complicated, so anything that can help you manage that complexity is a welcome bonus.
As you may already know, when you enable the Theme Editor by creating a ‘theme.settings‘ file, you can parse your CSS files by making sure they have a suffix of ‘.css.liquid‘.
Now, as part of the CSS processing that gets initiated to deal with the Liquid tags, we’ve added a pass through the SCSS processor, which is part of the SASS CSS extensions. You can read more about these CSS extensions at http://sass-lang.com
By using the CSS extensions, you can simplify your stylesheets by using variables, conditional logic, mixins and templates, nested attributes and a whole lot more. Even better, at the end of the processing you get a compressed CSS file so you can ensure that your site loads as fast as possible. Even if you don’t use any of the CSS extensions, you still get a compressed stylesheet, so that’s got to be something to smile about!
