CSS Introduction

A CSS framework is a library allowing for easier, more standards-compliant web design using the Cascading Style Sheets language. 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.

However, the first reset style sheet, created in 2004 by Tantek Çelik, included additional features such as setting all font sizes to 1em and removing link underlines and borders.

This process has gradually been refined by various developers, so that only some elements are reset to their basic appearance.
