Question 1

What is grid-template-areas?

Accepted Answer

grid-template-areas is a CSS property that lets you name regions of a grid and lay them out visually using ASCII-art-like strings. For example, "header header
sidebar main
footer footer" creates a classic header-sidebar-main-footer layout without needing to calculate column or line numbers.

Question 2

How do I merge cells into a named region?

Accepted Answer

Click a cell to select it, then click adjacent cells to add them to the selection. Type a name (like header or sidebar) and press Enter — every selected cell becomes part of that named region. The tool automatically keeps regions rectangular and valid.

Question 3

Can I create responsive layouts?

Accepted Answer

Yes. After building your desktop layout, click the Generate media queries toggle to get a ready-to-edit mobile breakpoint. You can also export the layout for tablet and phone widths by adjusting rows and columns then copying each variant.

Question 4

Does the generated CSS include column and row sizing?

Accepted Answer

Yes. The output includes grid-template-columns, grid-template-rows and gap alongside grid-template-areas, so you can paste it directly into your stylesheet. You can switch between fr units, fixed pixels and auto sizing from the controls.
