How to Add a CSS File to HTML
HyperText Markup Language (HTML) defines what the different pieces of a web page are. The Cascading Style Sheets (CSS) coding language describes what those pieces should look like. A CSS file can be added to HTML as an external style sheet, CSS included in a separate file from the HTML, or an internal style sheet, CSS included within the HTML file.

Steps

Add an External Style Sheet to HTML

Create the CSS file. Prepare and save your CSS file with the ".css" file type.

Upload your CSS file to your website.

Therefore a URL of "http://mysite.com/css/default.css" would be shortened to "/css/default.css". You must include that leading slash ("/"). This is called a relative path.

Add a link to the file. Find the tag in your HTML file, and create an empty line just above the tag. Add to that empty line, changing "www.your..." to the link to your CSS file.
