mm on "[Plugin: Contact Form 7] Contact form 7: How to style "choose file" button?"

Hello Arvind,

here is some code:

this is how i modified the look of the submit button in my contact form number 1

.contact-submit input {
	width: 100px;
	height: 30px;
	background-color: #999999;
	font-size: 13px;
	color: #fff;
	border: 1px solid #fff;
	border-radius: 7px;
}

this is how i changed the size of the contact form 2

#wpcf7-f482-t1-o1 .wpcf7-form
input.wpcf7-text {
	height: 20px;
	width: 200px!important;
}

I don't manage to modify the submit button by doing something like:

#wpcf7-f482-t1-o1 .wpcf7-form
input.wpcf7-file{
	width: 100px;
	height: 30px;
	background-color: #999999;
	font-size: 13px;
	color: #fff;
	border: 1px solid #fff;
	border-radius: 7px;
}

Any help would be greatly appreciated. Thank you.
