When you are using a framework such as Bootstrap, a CSS preprocessor is going to be involved. They enhance the vanilla CSS and add functionality such as use of variables, mixins and nesting of rules. Let’s look at two popular CSS preprocessors. LESSBootstrap is written in LESS. Here is an example of LESS, copied directly from the page linked above: 1. There are two flavors of SASS. The one you use is completely up to you, based on your preferred delimiter style. SASSSASS uses whitespace to nest CSS rules. There is also no place for semicolons in SASS. For example: 1. 23. In fact, you can actually change the extension of a CSS file to scss and run it through a preprocessor and it will compile just fine. One big difference is, although you can write the same CSS code you are used to, you can also nest your rules. The example above would be written in SCSS as: 1.
