When to Use CSS Grid

• Scenario 1: You need a complex, multi-dimensional layout (e.g., a dashboard or portfolio).
• Scenario 2: You want precise control over rows and columns.
• Example Code:cssCopy.container { display: grid; grid-template-columns: repeat(3, 1fr); gap: 10px; }

When to Use Flexbox

• Scenario 1: You need to align items in a single row or column (e.g., a navbar or card list).

Combining CSS Grid and Flexbox

• Why Combine Them? Use Grid for the overall layout and Flexbox for smaller, internal components.
• 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; }

Tips for Using CSS Grid and Flexbox

1. Start Mobile-First: Use Flexbox for simpler layouts on mobile and add Grid for more complex designs on larger screens.
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

1. Overusing Flexbox for Grid Layouts: Flexbox isn’t ideal for complex, two-dimensional designs.
2. Ignoring Browser Support: While modern browsers support both, always test your layouts in older browsers.
3. Not Using Semantic HTML: Pair your CSS with clean, semantic HTML for better accessibility.
