How to customize the Login Element button

At the moment we do not have an admin option to customize the button our our login element.  

However, you can use Custom CSS to modify the button if you're familiar with a little CSS (alternatively find a developer to assist with these modifications)
 
You would need to add this to Page Settings > Other Scripts > Custom CSS
 
div.ws-plugin--optimizemember-pro-login-widget>form input[type="submit"] {
background: #ff6600;
border: none;
font-size: 20px;
padding: 10px;
color: #fff;
}

To tweak the button you would modify the
Background: #ff6600  << change this value to a different colour hex code to change the background of the button
