How to change Contact form 7

Hi everybody
I changed the contact form 7
How can I change the Browse… button
I want to be the same as the Send button
Thank you

Add the class .wpcf7-submit to the buttons when you create them in the form builder.

This is the code for button but not for Browse…
.wpcf7 input.wpcf7-submit{

-webkit-transition: 0;
-moz-transition: 0;
-o-transition: 0;
transition: 0;
border: none;
position: relative;
color: #fff;
text-shadow: 1px -2px 0px black;
text-transform: uppercase;
-webkit-border-radius: 10px;
-moz-border-radius: 10px;
border-radius: 10px;

Thank you
