I'm trying to build a website with Weebly. I am currently searching the web far and wide to try to figure out how to create a sticky navigation bar and insert it into the style sheet, but everything I try won't work. I have a website header with the logo, and then below that is a separate table with the navigation. It either stays in the place it is with a big space between it and the top, or it stays at the top but some of the header is hidden. Also, when one scrolls, it appears behind the text and content. Any fix for my problems? Help!
