Best Practices​

  1. Use only when necessary – Prefer margin/padding for simple spacing
  2. Keep consistent sizes – Apply standard spacing values across the interface
  3. Responsive design – Use relative units (vh, %, em) when targeting multiple screen sizes
  4. Combine with layouts – Works best when used in grid or row containers

Accessibility Considerations​

  • Spacer has no impact on accessibility tools
  • Ignored by screen readers
  • Does not affect keyboard navigation

Performance Tips​

  • Very lightweight, minimal rendering cost
  • Use static sizes where possible for predictable layouts

Troubleshooting​

Spacer not visible

  • Check visible property is set to true
  • Ensure height is configured with valid CSS units

Unexpected size

  • Verify container styling does not override spacer height
  • Inspect computed CSS with developer tools

Class not applied

  • Remove commas in class names
  • Ensure CSS class definitions exist
