What is CSS?

CSS stands for Cascading Style Sheets

Styles define how to display HTML elements

External Style Sheets can save a lot of work

External Style Sheets are stored in CSS files

Styles were added to HTML 4.0 to solve a problem

Styles are normally stored in Style Sheets

Multiple style definitions will cascade into one

To solve this problem, the World Wide Web Consortium (W3C) - responsible for standardizing HTML - created CSS in addition to HTML 4.0. With HTML 4.0, all formatting can be removed from the HTML document and stored in a separate CSS file.

There are three parts for CSS syntax: a sector, a property and a value.

The sector is normally the HTML elecment or a tag which can be defined and property is the attribute which can be changed and each property can be taken a value. The property and value are separated by a colon, and surrounded by curly braces.

Syntax:- Sector { property:value}

Example :- body {color:black}
