I have an idea on how to build these from scratch but wanted to get your feedback. Maybe there’s a quicker way?
On the website https://fb.org1 there are 4 images about 1/2 way down, each with a title, background opacity and hover effect.
In the screencast below I show how we can use Columns element in Oxygen with a Superbox element in each and tweak it with a little bit of custom CSS to have a full-width 4-column section with each column showing a linked image + a title at the bottom.
We will set a translucent dark background so the title text can be seen and add a hover effect for the hyperlink to change the opacity of the image in each box.
