I'm creating this tabber+infobox to fill a need on GuP wikia, however I'm not being able to make it behave like an infobox, make it stand on the right side of the screen and make the text content sit on its left side.

Here is the JS and CSS.

i have already tried many things, from div to CSS center class, nothing worked.

Thx for any help.
