Suppose you have 2 Texts.
You want: when users click on each Text > Show Gallery Block.
#1. First, you add a Text Block with some text/url.
Make sure the option “Open link in new tab” is disabled
- #team01
- #team02


and 2 Gallery Blocks below.

#2. Install Squarespace ID Finder to find the ID of the Image Block.
In my example, we will have:
- Left Gallery: #block-yui_3_17_2_1_1714699207155_19750
- Right Gallery: #block-yui_3_17_2_1_1714699207155_20357

#3. Use 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(){
// Team 01
$("#block-yui_3_17_2_1_1714699207155_19750").closest('.fe-block').addClass('team01 show');
// Team 02
$("#block-yui_3_17_2_1_1714699207155_20357").closest('.fe-block').addClass('team02');
// Team 01
$('a[href="#team01"]').click(function(){
$(".team01").addClass("show");
$('.fe-block:not(.team01)').removeClass('show');
}
);
// Team 02
$('a[href="#team02"]').click(function(){
$(".team02").addClass("show");
$('.fe-block:not(.team02)').removeClass('show');
}
);
});
</script>
<style>
.team01 .gallery-block, .team02 .gallery-block {
display: none;
}
.show .gallery-block {
display: block !important;
}
.show {
z-index: 999999 !important;
}
</style>

#4. Explain code
