How to add an external stylesheet
With stylesheets becoming the norm in web layout and design, the best way to attach these to your site it externally. This means totally splitting the html from the css. To do this we need 1 link of code that is placed in the head tag <head>, this tag is:
<link rel=”stylesheet” href=”style.css” type=”text/css”/>
All you have to do is use the same code as above and either name your stylesheet to style.css or change the href value to the name of your stylesheet.
