Order Summary Card Mobile-first CSS Grid, Flexbox

How did you remove scrolling? There are 2 options:

• Set margin: 0 to body tag. I recommend this approach
• Set overflow: hidden to body tag

Also your background doesn't stretch to full width

If you're publishing your code on Github, I recommend to use Github Pages to host there your working application. Thus you will keep both code and demonstration in one place

Try to set the height: 100vh; to the body tag to remove the scrolling. I hope this will be helpful. body { height: 100vh; }
