Center Underline

Underline & Decoration · Animated · pure CSS

A solid underline bar grows outward from the center to full width, holds, then retracts. Origin-from-center sets it apart from slide and dash underlines.

Center Underline

How it works

Center Underline 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

Center Underline exposes 4 dedicated controls — Hue, Thickness, Gap 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

/* Center Underline — generated with TEXT-FX
 * 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: 900;
  letter-spacing: 2px;
  text-transform: none;
}

.text-effect {
  display: inline-block;
  color: hsl(193 25% 92%);
  padding-bottom: 17px;
  background-image: linear-gradient(hsl(193 90% 62%), hsl(193 90% 62%));
  background-repeat: no-repeat;
  background-position: center 100%;
  background-size: 0% 9px;
  animation: text-effect-grow 3.2s ease-in-out infinite;
}

@keyframes text-effect-grow {
  0% { background-size: 0% 9px; }
  40%, 60% { background-size: 100% 9px; }
  100% { background-size: 0% 9px; }
}

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