I know very little about HTML and CSS but I've been able to decipher most of what I've needed to know based on trial and error. I had a friend coding me a website long ago and he abandoned the project but gave me what he had finished. I modified it to fit my needs, but now I'm at a stop. I have these sliding gallery tabs that I need to be able to click and they will open the galleries below them. I know I need to add in some sort of CSS container...
