So, I'm making these tabbers for a template, and I've been trying to get them to align in a horizontal line like tabbers usually do, but for the life of me, I can't figure out what I'm doing wrong. Can someone take a look at the CSS?

This is the tabber itself. And this is the CSS page in which the tabbers' CSS is located on.
