Weight Wave

Entrance & Kinetic · Animated · pure CSS

Each letter's variable-font weight swells light to heavy and back, offset by index so a wave of boldness rolls across the word (Recursive wght axis).

How it works

Weight Wave is an animated entrance & kinetic text effect rendered entirely in CSS. Each character is wrapped in its own span so it can animate independently — the HTML and JSX exports include that per-letter markup.

Controls

Weight Wave exposes 4 dedicated controls — Hue, Light, Heavy 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

/* Weight Wave — generated with TEXT-FX
 * HTML: each character is wrapped in a <span> — see the HTML export.
 * Font: 'Recursive', sans-serif (load from Google Fonts).

.text-effect {
  font-family: 'Recursive', sans-serif;
  font-weight: 700;
  letter-spacing: 4px;
  text-transform: none;
}

.text-effect {

.text-effect .fx-ch {
  display: inline-block;
  font-variation-settings: 'wght' calc(449 + var(--i) * 46);
  animation: text-effect-wwave 2.3s ease-in-out infinite;
  animation-delay: calc(var(--i) * -0.12s);
}

@keyframes text-effect-wwave {

}

HTML

This effect needs the markup below (per-letter spans, SVG defs, or a data-text attribute).

<style>
.text-effect {
  font-family: 'Recursive', sans-serif;
  font-weight: 700;
  letter-spacing: 4px;
  text-transform: none;
}

.text-effect {
  color: hsl(60 55% 80%);
  white-space: pre;
}
.text-effect .fx-ch {
  display: inline-block;
  font-variation-settings: 'wght' calc(449 + var(--i) * 46);
  animation: text-effect-wwave 2.3s ease-in-out infinite;
  animation-delay: calc(var(--i) * -0.12s);
}

@keyframes text-effect-wwave {
  0%, 100% { font-variation-settings: 'wght' 449; }
  50% { font-variation-settings: 'wght' 860; }
}
</style>
