Question

HTML

Tell me how to make such a block
1. When setting Col- blocks stick together, but you need an indent, if you make a margin, the block goes down. In fact, you need a distance and that they be in the center of the container.
2. How to set an image as a clipping mask?

Answer 1

Set col not 6 and 6, but 5 and 5 and margin.
Or col by 5 and offset 1 on the right side.
