If a word (e.g.THIS_PHRASE_HERE) overflows its inner div (fixed width), I want to split it with an underscore. I know I can useword-break:break-allto split a word on any character, but that seems a bit confusing, especially if there are 1 or 2 character orphans at the end. I'm sure I can do this with JS, but was wondering if there's a way to do it just in CSS, likeword-break: "_".
