Upload button styling

https://www.jotform.com/build/73258991513868

Is there a way to change the text on this upload button or can somebody at least tell me the CSS id/class for it? Would like to make it bigger, change colour, add padding and centered.

Cheers!

It is not possible to style the Single file upload button. Single file upload is browser inherited, it changes its layout, style and text depending on the browser you used. Each browser has a different rendition of this field.

If you want to style the upload field button, you have to enable Multiple Styles option.
