CSS Navigation is a kind of a link effect, but it look much more professional to use in your main menues. CSS Navigation very hard for beginners to understand, and I struggled in the beginning, but if you know CSS and HTML this is not going to be a big problem.
1. Copy and place this code anywhere you'd like to in your CSS code.
2. To make links, copy this code and change where it says URL HERE and NAME HERE with whatever you want.
