Cascading Style Sheets (CSS) allows developers to change a whole website at once, rather than making changes to each page. This is done through each page linking to a style sheet that controls the display of each page.
By creating one page of CSS code which contains all the colors, fonts, backgrounds and other design elements of a website, and linking to that page, CSS enables the developer to take control of the design aspects of the site. CSS also allows you to control the placement of graphic elements, add rollover effects, control the spacing between letters, lines, margins, etc. If you aren’t already using CSS, save yourself some time and effort and give it a shot.
