What does the fr unit mean in CSS Grid?

The fr unit stands for 'fraction' and represents a share of the available space. Setting grid-template-columns: 1fr 2fr creates two columns where the second is twice as wide as the first. Fr units distribute remaining space after fixed-size columns are calculated.

When should I use CSS Grid instead of flexbox?

Use CSS Grid for two-dimensional layouts with both rows and columns, like page structures, dashboards, and image galleries. Use flexbox for one-dimensional layouts — a single row or column of items. Grid handles complex overlapping areas; flexbox handles distribution and alignment of items.

What are grid-template-areas?

Grid-template-areas let you name regions of your grid and place items using those names. For example, grid-template-areas: 'header header' 'sidebar main' creates a two-row layout with a full-width header and a sidebar-main split. This makes your layout code self-documenting.

How do I make a responsive grid?

Use repeat(auto-fill, minmax(250px, 1fr)) for your columns to create a responsive grid that automatically adjusts the number of columns based on available space. The minmax() function ensures items are at least 250px wide but expand to fill remaining space.

Can items span multiple grid cells?

Yes, you can use grid-column: span 2 to make an item span two columns, or grid-row: span 2 to span two rows. The visual generator lets you click and drag across cells to create these spanning areas automatically.
