Responsive grid not working

Hi everyone

I’m trying to follow this tutorial to make a grid responsive: https://youtu.be/4u1sD7GcGoQ?t=253

Even though I have followed all instructions, my grid does not adjust the number of columns and rows when the viewport width is changed:

Switch to the tablet breakpoint and remove the fixed width from the ‘‘Services Grid Copy’’ and set it to auto.

Thanks! Removing the fixed width solved the issue.
