Width CSS not working

Hi there, to make my form appear on a single line and adjust the widths of the boxes I’ve added the custom CSS to my stylesheet:

.mc4wp-form label,
.mc4wp-form input[type="text"],
.mc4wp-form input[type="email"] {
	display: inline-block !important;
	width: 45%;
}

But whilst I can see that the boxes are trying to line up, the widths are not being affected by the second part of the code (have tried it with several different numbers).

You can see my efforts at http://freemindproject.wpstagecoach.com

Thanks for any thoughts…
