CSS on an input field

I’m trying to style a text field form input element, but it doesn’t seem to have any effect.
Specifically border, font-size, and background-color. Is there anyway to change these values, and is there a list of supported properties per element anywhere?

text fields accept a limited amount of styling at the moment: https://adobexdplatform.com/plugin-docs/reference/ui/elements/textfields.html#styling

Just to add, there’s a uxp-quiet="true" attribute for text fields that will swap out some of the default styling.
