External CSS

When using CSS it is preferable to keep the CSS separate from your HTML. Placing CSS in a separate file allows the web designer to completely differentiate between content(HTML) and design(CSS). External CSS is a file that contains only CSS code and is saved with a ".css" file extension.

• It keeps your website design and content separate.
• It's much easier to reuse your CSS code if you have it in a separate file. Instead of typing the same CSS code on every web page you have, simply have many pages refer to a single CSS file with the "link" tag.
• You can make drastic changes to your web pages with just a few changes in a single CSS file.
