Highlighter

Underline & Decoration · Animated · pure CSS

A marker highlight sweeps in behind the text like a felt-tip pen. Draws attention to a phrase with a hand-made feel.

Highlighter

How it works

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

Controls

Highlighter exposes 3 dedicated controls — Hue, Band Height and Speed — 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

/* Highlighter — made with TEXT-FX · https://text-fx.app
 * HTML: just put the class on any element.
 * Font: 'Major Mono Display', monospace (load from Google Fonts).
 */

.text-effect {
  font-family: 'Major Mono Display', monospace;
  font-weight: 400;
  letter-spacing: 8px;
  text-transform: uppercase;
}

.text-effect {
  display: inline;
  color: hsl(170 30% 8%);
  padding: 0 0.12em;
  background-image: linear-gradient(hsl(170 45% 72% / 0.4), hsl(170 45% 72% / 0.4));
  background-repeat: no-repeat;
  background-position: 0 56%;
  background-size: 0% 44%;
  box-decoration-break: clone;
  -webkit-box-decoration-break: clone;
  animation: text-effect-wipe 2.2s ease-out 1 forwards;
}
.text-effect:hover {
  animation-name: text-effect-wipe-r;
}

@keyframes text-effect-wipe {
  0% { background-size: 0% 44%; }
  100% { background-size: 100% 44%; }
}
@keyframes text-effect-wipe-r {
  0% { background-size: 0% 44%; }
  100% { background-size: 100% 44%; }
}

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