How to create a CSS3 document
There is no real difference in creating a CSS3 document when comparing CSS3 with CSS2.1. It all starts with creating a link in the head section of the HTML document which will call up the CSS3 document. Next, Notepad needs to be opened and the document needs to be saved as style.css (this CSS document can be given any desired name) in the same folder where you have saved the HTML document. If the head section link refers to the correct CSS3 document location the chosen style will be applied.
