💡 Border Radius Best Practices

🎯

Consistency

Maintain consistent border-radius values across similar elements for a cohesive design.

Responsiveness

Consider using relative units (%, em, rem) for responsive designs.

🎨

Visual Hierarchy

Use larger radii for interactive elements like buttons to make them more inviting.

⚡

Performance

Excessive border-radius can impact rendering performance - test on target devices.

🔄
