I can see the site now 🙂
So the section is built with GenerateBlocks, if you are using GenerateBlocks Pro plugin, there’s a built-in option to add a container link.
If you don’t have GB pro, try adding an additional CSS class to the container block, eg. container-with-link, then add this CSS:
.gb-container.container-with-link {
position: relative;
}
.gb-container.container-with-link a:before {
content: "";
position: absolute;
top: 0;
right: 0;
bottom: 0;
left: 0;
z-index: 0;
}
