The text box for CSS and HTML seems unnecessarily narrow and I’d also like to be able to resize its height (and have that change persist) or have it autosize.
Do you know about our Edit in Visual Code-plugins? It is basically editing CSS/HTML inside Visual Code which gives you syntax-coloring, keyword completion etc. As a bonus, you can keep the editor open, and even if the selection changes the values (css or html) are written to the original cell.
Oh nice, that’s great to know about. For the record, I mainly use CSS for applying flex and grid properties, as well as multiple background shadows, all of which would be nice to see as UI controls.
