Glow Outline

How it works

Glow Outline is an animated outline & stroke text effect rendered entirely in CSS. It works on a single element — just add the .text-effect class, with no extra HTML.

Controls

Glow Outline exposes 4 dedicated controls — Hue, Stroke, Glow and Flicker — on top of the shared type controls (font, weight, letter-spacing and case). Open it in the generator to tune every value live, then copy the updated CSS.

CSS

/* Glow Outline — generated with TEXT-FX
 * HTML: just put the class on any element.
 * Font: 'Space Grotesk', sans-serif (load from Google Fonts).
 */

.text-effect {
  font-family: 'Space Grotesk', sans-serif;
  font-weight: 700;
  letter-spacing: 0px;
  text-transform: none;
}

.text-effect {
  color: transparent;
  -webkit-text-stroke: 3px hsl(103 95% 62%);
  filter: drop-shadow(0 0 13px hsl(103 100% 60% / 0.95)) drop-shadow(0 0 26px hsl(103 100% 60% / 0.95)) drop-shadow(0 0 49.4px hsl(103 100% 60% / 0.95));
  animation: text-effect-flicker 3.5s steps(1, end) infinite;
}

@keyframes text-effect-flicker {
  0%, 100% { opacity: 1; }
  41% { opacity: 1; }
  43% { opacity: 0.35; }
  45% { opacity: 1; }
  72% { opacity: 1; }
  74% { opacity: 0.5; }
  76% { opacity: 1; }
}

Pure CSS — just add the .text-effect class to any element.
