Questions about CSS Shadow & Grid Generator

What CSS does it generate?

Standard, copy-ready CSS: a .box rule with background, border-radius and box-shadow, or a .grid rule using display:grid with grid-template-columns and gap. No vendor prefixes are needed for these properties in modern browsers.

Can I use the grid CSS on a real site?

Yes. The grid rule uses repeat() and fractional columns, so it is responsive. Paste it into your stylesheet and put your content inside the grid container.
