Why Use Cascading Style Sheets (CSS)?
Most organizations addressing accessibility in web design, such as the World Wide Web Consortium, recommend that you separate layout (the structure or presentation of a page) from the content.
We recommend using an external CSS to control appearance and style without sacrificing accessibility. An external CSS is a simple text file, with the extension .css, that includes specifications of how different elements within an HTML page should appear.
There are four main benefits to CSS:
- text on a page is completely accessible for blind users because formatting code doesn’t get mixed up with content
- pages load faster because they don’t have to load font, color, and other descriptions for text
- visitors to your site can link to their own style sheets to satisfy their own special needs
- you can make global changes to a site quickly and easily
