  3. Explanation:

    • Grid Container: The .grid-container div is defined as a 3x3 grid with 3 columns and 3 rows, each row 100px in height.

    • Individual Items:

      • Item 1 spans across two columns using grid-column: 1 / 3;.

      • Item 2 spans two rows and two columns using grid-column and grid-row.

      • Item 3 spans two columns with grid-column: span 2;.

      • Item 4 uses the named area approach.

  4. Testing:

    • Open first-grid.html in a browser to see how the grid items are positioned and the effect of spanning columns and rows.
