Connecting HTML and CSS
When you want to CSS to your HTML, you need to add a separate file, called a stylesheet. You will put your CSS in this file. Then, in your HTML's <head> element, add the following tag:
<link rel="stylesheet" type="text/css" href="main.css">
main.css should be changed to whatever the name of your stylesheet is. It should have the extension .css, but otherwise can be named whatever you want.
