About Neon Border Effects

Neon border effects are created using a combination of CSS properties to simulate the glowing appearance of neon lights. The main techniques used are:

Key Components

  • Border: Defines the base shape and color of the neon effect
  • Box Shadow: Creates the glowing effect around the border

Best Practices

  • Use vibrant, saturated colors for the most realistic neon effect
  • Balance glow intensity with spread for a natural look
  • Test different border widths to find the right balance

Browser Support

  • Box-shadow effects work in all modern browsers
  • Consider providing fallback styles for older browsers

Performance Tips

  • Use transform: translateZ(0) to enable GPU acceleration
  • Avoid excessive shadow blur values
  • Use will-change: opacity, transform for smoother performance
