Hex codes for common HTML elements

When adding HTML elements in content via CSS, you need to add the hexademical code instead of the HTML code. I'll list new ones as I need them.

(») » = "\00BB"
( )   = "\00A0"

The actual hex would be %BB, %A0, etc. But when putting that in CSS you use \00 instead of %. Example:

a:after{
  content:"\00A0\00BB";
}

This produces " »" after the link.
