I’m making the suggestion here as well, as requested by Alan Cutter:
Which is to allow the following CSS to automatically change the height of a <textarea> depending on its content:
textarea {
height: max-content;
}
This is related to the iframe resize and height animation requests:
Where I also have a working demo:
https://craigfrancis.github.io/iframe-height/additional/textarea/
I support adding something like this on textarea. It’s not clear to me that it should be a CSS feature though. I think an attribute on textarea would make more sense to me since this is really just trying to fix that textarea has some special sizing rules. I also think an attribute on textarea is more discoverable.
In either case, I don’t feel strongly about the color we paint the bikeshed, so I’d easily be swayed if other browser vendors felt differently or if there was a strong web developer sentiment for a particular solution.
It depends, while a <textarea> does have the rows/cols attributes, normally styling is done with CSS, that’s the only reason I think it falls under the CSS group.
The autoresize feature is purely presentational (e. g. doesn’t make sense for voice browsers), so it’s certainly of CSS responsibility.
