Link to an External Style Sheet

You need to first create a page and name it something such as stylesheet.css - this can be done on notepad. Just make sure that it isn't a text document (save it's file type as ~~all documents~~), and then name it stylesheet.css.

Put this code on every page that you want your CSS to have affect on:

The bolded part is where your stylesheet's name will go. Then, if done correctly, it will work!

This next part I give credit to Lissa Explains for explaining.

Here is a sample, ~~remember not to add the style tags~~ to your text file (external CSS):

A:link
{ text-decoration: none; }

body
{ background-color: #000000; }

And that's it! If you need help on anything related to this, just email me! I'll try to answer your questions and make it easier for you to learn. :)
