To adjust the layout for different screen sizes:
Click ‘Edit Block’ or ‘Edit Section’ in the editor.
On the right side, find the fields where you can enter values.
Each field has a ‘Enable Responsive Mode’ icon—hover over it and enable it.
Adjust values separately for mobile, tablet, and desktop by switching screen sizes in the top-center of the editor.
Make adjustments until you're happy with the design!
