Grid problem on mobile breakpoint

Hello, I’m doing my learning project and I’ve run into a problem with the mobile breakpoint.

On the desktop version, everything looks like what I need it to look like but the mobile breakpoint is driving me crazy.

Please help me how can I make it look like on the mockup.
