Ever find yourself wishing that CSS had features like variables, functions, or reusable classes? Look no further. LESS and Sass are CSS style sheet tools called preprocessors that add these features and more, simplifying the creation of complex CSS styles. In this course, author Joe Marini introduces the LESS and Sass tools in a two-part manner.
The first section focuses on LESS (Leaner CSS) and how it can be used on both the client and the server. The lessons show how to work with variables, mixins, nested rules, and other features to easily create maintainable CSS.
The second section introduces Sass (Syntactically awesome stylesheets), which contains many of the same features as LESS, along with a few new ones. Joe also compares and contrasts the two tools, and explains how your platform and needs may influence which tool you choose.
(music playing) Hi I'm Joe Marini, and I'd like to welcome you to CSS with LESS and Sass; two great tools for building CSS, using features that you've always wished that CSS had built in. I'll start by showing you how to install the tools you'll need to work with LESS, and Sass. Then we'll see how to use each tool to build CSS code using features, such as variables, which allow you to define values once, and then reuse them throughout your style rules. We'll see how to create reusable classes called Mixins; groups of style rules that can be parameterized, and included inside of other styles.
We'll even see how to use functions, and mathematical operations in CSS to create advanced visual effects. If you're ready to take your CSS styles to the next level, then let's get started learning how to build great CSS with LESS and Sass.
