The Inster Block has several parameters relating to responsiveness. You can set the size (in pixels) if the width of one image in the grid becomes less than this number, then the number of columns in the grid will be reduced by one.
Additionally, you can turn on rebuilding the grid in a single column on mobile phones or tablets.

The block above has a size of 6 X 2. The grid will be reduced by a certain number of columns so that the width of each of the posts is not less than 200px. On mobile phones, the grid will be rebuilt in one column.

Grid is brilliant for creating grids, but it doesn’t mean that our other layout tools are no longer necessary. Responsiveness of the Inster Block allows you to create incredibly flexible layouts with a grid that looks awesome on all devices.

A variety of settings allows you to customize the block to the smallest detail. In the settings, you can select initial animation and one of the hover styles and also choose from preset color schemes or choose from 16 million colors independently. There is a mode for displaying enlarged posts in Lightbox, which can be turned off.
