1. Drop in the "Grid" stack into your page

Set the amount of boxes you require and link each one to the right webpage
2. Drop in your images and edit the titles.

Drop in your images or Icons. The Stack automatically resizes images but best to keep them all the same dimension ratio so that it all fits together nicely on the page. But irregular dimension ratios work OK - just it won't look uniformed. The images will be different heights. Still a nice effect. Depends what you are after. If any adjustments are needed, use the mini adjustments options.
Adjust colours and edit the title and sub header or category text fields. Then preview and publish!
