CSS hover submit button

Hi,

I want to have a specific style for the submit button so I have added the class ‘verzenden’ to the code: [submit class:verzenden "Verzenden"]

In the css I added the following:

.verzenden {
	background: #f2a035;
}

Now, when I hover on the button it disappears…
What can I do about the style of the class to show the button when hovering?
