uBlock (and AdBlock Plus) can access and prune/block individual DOM elements, and even has a built-in tool (the eye dropper icon) to select and block them. I think they call it "cosmetic filters". It's also available in the right-click context menu under "Block element". I don't know exactly how it works under the hood, though. If I block a div with text in it, I know the div is still downloaded, just not displayed. I don't know what happens in more complicated cases, like if I block a div that contains an img tag. I think it's smart enough to prune the img tag before the browser downloads it, but IDK for sure. I vaguely recall Privoxy having some kind of content filtering, but when I tried it, it wasn't html/css/javascript aware, and only did regex based replacement.
