File: SASS_REFERENCE — Sass Documentation Sass is an extension of CSS that adds power and elegance to the basic language. It allows you to use variables, nested rules, mixins, inline imports, and more, all with a fully CSS-compatible syntax. Sass helps keep large stylesheets well-organized, and get small stylesheets up and running quickly, particularly with the help of the Compass style library. Features Fully CSS-compatible Language extensions such as variables, nesting, and mixins Many useful functions for manipulating colors and other values Advanced features like control directives for libraries Well-formatted, customizable output

The 30 CSS Selectors you Must Memorize So you learned the base id, class, and descendant selectors—and then called it a day? If so, you're missing out on an enormous level of flexibility. While many of the selectors mentioned in this article are part of the CSS3 spec, and are, consequently, only available in modern browsers, you owe it to yourself to commit these to memory. And by the way, if you're having trouble with your CSS and want a pro to look over it and fix any errors, you can find some qualified freelancers on Envato Studio. Let's knock the obvious ones out, for the beginners, before we move onto the more advanced selectors.
The Future Generation of CSS Selectors: Level 4 Back in January 2014 I wrote the article The Current Generation of CSS3 Selectors. The goal of that article was to introduce the new generation of selectors that often fell under the “CSS3” umbrella. That group of selectors has been well documented in a lot of places, and browser support for those features is quite strong (all browsers including IE9+). The future of CSS selectors is also looking bright, with the Selectors Level 4 specification currently in Working Draft status, and an Editor’s Draft of the same spec still in progress (the editor’s draft is generally viewed as more authoritative). This article will focus on the new selectors not discussed in my previous article. Browser support for many of these is pretty poor, so I don’t recommend using many of these in production.
Flexible CSS cover images I recently included the option to add a large cover image, like the one above, to my posts. The source image is cropped, and below specific maximum dimensions it’s displayed at a predetermined aspect ratio. This post describes the implementation. Demo: Flexible CSS cover images Known support: Chrome, Firefox, Safari, Opera, IE 9+ 39 Web Apps and Tools We Use to Create Websites Probably not unlike you, we use a cadre of different tools to help us create websites and products we’re proud of. Every year it seems that this list morphs, evolves, shrinks and grows. So we thought, ‘Hey, it might be valuable to some people to get a look at how we build things and the tools that we use to get the job done.’ We looked at every step of our development process and highlighted our favorite technologies every step of the way.
