CSS framework

From HandWiki
Short description: Library allowing for more standards-compliant web design

A CSS framework is a software library allowing for easier, more standards-compliant web design using Cascading Style Sheets. Most of these frameworks contain at least a grid. More functional frameworks also come with more features and additional JavaScript based functions, but are mostly design oriented and focused around interactive UI patterns. This detail differentiates CSS frameworks from other JavaScript frameworks.

Two notable and widely used examples are Bootstrap and Foundation.

Modules and tools offered by CSS frameworks include:

Bigger frameworks use a CSS interpreter such as Less or Sass.
