Can I have see-through text on button?

Hi there,

My website has an animated gradient background and I’d like the buttons to have a white fill and the text on the buttons to be see-through.

Do you have any idea if this can be achieved?

I tried some custom CSS, but it still doesn’t work.

Thanks in advance!
