Tangent: On the note of web based text field for "normal users", what's the best UX you can get while also trying to be as no-JS-friendly as possible? Are there CSS-only tricks to make editing in an input field nice? I'm making a low-JS site, but it also has a lot of input fields, user content generation, etc. In "modern CSS" i feel like Input boxes should be better than they are. Is JS the only way?
In general, :has and :user-invalid are new and can be useful styling forms.
