Hover header image

Hi there,

You'll need to add your header using HTML in GP Hooks.

1. Remove your header in the Customizer.
2. Add something like this into the "Before Header Content" hook in GP Hooks:

<div class="custom-headers">
    <div class="header-1">
        <img src="URL TO HEADER 1" alt="" />
    </div>
    <div class="header-2">
        <img src="URL TO HEADER 2" alt="" />
    </div>
</div>

3. Add this CSS:

.custom-headers .header-2,
.custom-headers:hover .header-1 {
    display: none;
}

.custom-headers:hover .header-2 {
    display: block;
}

That should get you started :)
