When to Use CSS Grid

• Scenario 1: You need a complex, multi-dimensional layout (e.g., a dashboard or portfolio).

• Example: A responsive card layout where the grid defines the structure, and Flexbox aligns the content inside each card.
• Code Example:cssCopy.grid-container { display: grid; grid-template-columns: repeat(auto-fit, minmax(250px, 1fr)); gap: 20px; } .card { display: flex; flex-direction: column; justify-content: space-between; }

2. Use gap for Spacing: Both Grid and Flexbox support the gap property for consistent spacing.
3. Leverage Browser DevTools: Inspect and debug your layouts using browser developer tools.
4. Experiment with minmax(): Create flexible, responsive grids with the minmax() function.

Common Mistakes to Avoid
