Sure thing. So just as a precaution, I’d prefix that code with another CSS variable, to make sure it has top priority. I’ve adjusted the code for you below:
#wrapper div.wpforms-container-full .wpforms-form input[type=submit],
#wrapper div.wpforms-container-full .wpforms-form button[type=submit],
#wrapper div.wpforms-container-full .wpforms-form .wpforms-page-button {
background-color: #e02945;
border: 5px solid #fff;
color: #333;
font-size: 1em;
padding: 10px 150px;
}
#wrapper div.wpforms-container-full .wpforms-form input[type=submit]:hover,
#wrapper div.wpforms-container-full .wpforms-form input[type=submit]:active,
#wrapper div.wpforms-container-full .wpforms-form button[type=submit]:hover,
#wrapper div.wpforms-container-full .wpforms-form button[type=submit]:active,
#wrapper div.wpforms-container-full .wpforms-form .wpforms-page-button:hover,
#wrapper div.wpforms-container-full .wpforms-form .wpforms-page-button:active {
background-color: #f34640;
border: 5px solid #fff;
cursor: pointer;
}
Normally the best place to put the above code is inside your theme. However in this case I’m not familiar with that theme and it doesn’t appear to be using the common style.css, so I would recommend using a simple plugin.
Here is a great how-to and video that shows you how and where to place the code ??
