Suppose you have an Image Block and a Video block, and you want to hover over the image, the video block will appear.
#1. First, add an Image Block and a Video Block

#2. Edit the Image Block and add this URL:
- #video01
Make sure “Open link in New Tab” is disabled

#3. Install Squarespace ID Finder to find the ID of all Blocks
In my example, we will have:
- Image Block: No need to find ID
- Video Block: #block-yui_3_17_2_1_1714008816100_10815

#4. Use this code to Code Injection – Footer (or Page Header Code Injection)
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.7.0/jquery.min.js"></script>
<script>
$(document).ready(function(){
$('a[href="#video01"]').hover(function(){
$("#block-yui_3_17_2_1_1714008816100_10815").addClass("show");
}, function(){
$("#block-yui_3_17_2_1_1714008816100_10815").removeClass("show");
})
});
</script>
<style>
#block-yui_3_17_2_1_1714008816100_10815 {
display: none;
}
.show {
display: block !important;
}
.show {
z-index: 999999 !important;
}
</style>

#5. Explain code
