[Plugin: Contact Form 7] Customize file attach input

im having a weird problem
im creating a form as ussual
and everything is going ok until i create a attack file input
the problem im having is tha i cant apply a style to the input field but i can do it with the buttom to search the file
here is a cap of that input

IMG

as you can see
there is a style applied for all the input fields, and i create the same one for: “wpcf7-file” wich is the default for those kind of fields.

the problem is that when i apply a style, its applyed to the buttom, and not to the input

is it posibble to apply different style for both elements?
thanks a lot.
