How do I add sections with images?

How can I get the (3) images & text like this template has:

I’m talking about the 3 images (with text below them) below the main slider. Did I accidentally delete something? How can I set this up? Thank you!

If I undertand correctly what you ask, you can achieve this result with any grid framework.

Search Bootstrap for example, which is the most famous.

Thank you for the reply I’m checking it out. I’m just curious how the theme I’ve activated shows these grid items, yet I don’t see how to add them to my pages. I’m kinda new to wordpress.
