Why doesn't the block take up the full width of the screen?

Question

css

In the stucco-gal block, with a screen width of up to 768 pixels, the picture with the slides for some reason does not occupy the entire width of the screen. Moreover, the parent gallery-wrapper, in which stucco-gal is located, I set flex-direction: column and justify-content: center. I need it to be the same even square for the entire width of the screen, how can I do this?

Try setting your images to width: 100% and height: 100%
