Random #css question time, in the hope someone can save me from hours of experimentation!
I'm styling html I don't control, and I want to make a descendent element as wide as an indirect ancestor. Basically, there's "ancestor" (unknown width, not full viewport) > "some layers of divs" (narrower than ancestor) > "my thing" (I want this to be as wide as "ancestor"). Is this a thing it is possible to do with CSS?
@[email protected] Unfortunately I don't know the difference as a fixed number; the level inbetween has a max-width set (and desired by the user) so the difference between its width and the "ancestor" depends on current viewport width. I was hoping there was some cunning way to infer it in "modern" css (I poke UIs occasionally, but the last time I did it full time was over twenty years ago).
Turns out searching for "make thing the same width as other thing in CSS" is surprisingly hard to specify tightly enough to get meaningful search results. Who would have thought...
