The tree may grow more than the attached image but i think the concept should apply to bigger version of the tree if possible.
i`m attaching the sample of the tree image in case you don`t want to click on the link.

CSS isn't a programming language. It is only a list of style rules for HTML. You could likely create something that LOOKS like what you're asking with CSS, but if you want it to actually FUNCTION, you'll have to use an actual programming language.
