How does the neon glow work in CSS?

The glow is created by stacking multiple text-shadow declarations with the same hue but increasing blur radii. Outer layers are semi-transparent to simulate the soft halo of a real neon tube.

What animation options are available?

Three modes are available: Static (no animation), Flicker (irregular opacity keyframes simulating a faulty neon tube), and Pulse (smooth brightness oscillation using a CSS @keyframes animation).

Can I use this on any background colour?

The preview offers black, navy, and dark gray backgrounds. For your own project, neon effects work best on very dark backgrounds (luminance below 20%) — on light backgrounds the glow will be nearly invisible.

Which fonts work best for neon text?

Thin or light-weight fonts (font-weight 100–300) produce the most realistic look because the glow can surround a narrow stroke cleanly. The generator defaults to a system sans-serif; swap in a Google Font for more character.
