Sometimes you end up with a layout like this: +---------------+ |foofoofoofoo foofoofoofoo foofoofoofoofoofoofoofoo | | +---------------+ You either don't realize it's happening, because the element is on the right side of the screen (sidebar). or beginners might not know how to fix it. It might be nice to put a small warning icon on the text node or the element itself to say that it's happening, and some suggestions on how to fix it.

Hi ntim, We are trying to triage this. Some of the questions we wanted to know if there are currently MDN docs for learning more about overflows. Some potential issues we see is that we might end up showing too many unwanted warnings/clutter in the markup view that it becomes annoying, and maybe overflow is what the developer wanted. It is gonna require prototyping to figure out what we want in this case.

I couldn't find any MDN doc on this. But usually the issue is a result of either: - the element being too wide - white-space: nowrap usage, but without proper clipping - Forgetting to set overflow: auto (overflow: visible is the default value)
