These controls are always rendered using a "default style", ignoring any CSS rule. AFAIK, nothing is said on the CSS specification about this type of controls, so I do not expect to find any non-standard CSS rule to control the style of them. I propose to use CSS rules for input and button selectors for determining the style of these controls. Reproducible: Always Steps to Reproduce:

I expected borders and button background styles to be applied also to the file control. Instead, only text field background is applied.
