Contact Form7 – Style 'Choose File' button

Hi there

I am building a site – http://forcemodelsnyc.com – and on the ‘Apply’ page I am using a section for photo uploads which is built using contact form 7.

I am wanting to style the ‘Choose File’ button so that it displays an image as opposed to the standard button.

An example can be found here – https://getscouted.fordmodels.com/

I know this may be achieved by using a div id and I have checked the styling of fordmodels however I just can’t seem to so anything with this button whatsoever.

For reference it is currently set up on <div id=”apply” </div> but I can take this off if required.

Any help would be great
