Cascading Style Sheets

Cascading Style Sheets (CSS) are used with HTML to give a web page designers centralized control over the appearance of each page. CSS rules work best when stored in a stylesheet document, but style rules can also be embedded into a web page (in the header) or used inline (in a tag).

Format

All definitions in CSS are written as

selector {
property: value; 
}

For example, in order to change the background to red, and the text color to maroon, you would type,

body {
background:red;
color:maroon
}

Body is the selector - meaning you want to edit a characteristic of the body in html, background and color are the properties - background refers to the background color and color refers to the text color, and then red and maroon are the given values for those properties.
