How to add a link block to 3 individual circles?

Help needed.

I have 3 images of circles ( blue, green & red) next to each other in a div.
How can I add a link to each individual circle?


Here is my site Read-Only: LINK
(how to share your site Read-Only link)

Wrap each of the images in a link block.
You can right click it and see that option in the designer’s context menu.
