CSS Glitch Text Effect Generator

What it does

The CSS Glitch Text Effect Generator builds animated "glitch" text — the RGB-split, torn-band, VHS-error look — as a self-contained CSS + HTML snippet. Type your text, pick one of four effects, set the colors, the size, the intensity and the loop speed, and copy the two blocks into your project.

There is no image, no font file, no JavaScript and no animation library involved: the whole effect is text-shadow, clip-path, transform and a CSS @keyframes loop.

The four effects

• Chromatic Split — the two glitch colors slide either side of the glyphs on every frame, producing the classic mis-registered-print / anaglyph look. Subtle at low intensity, aggressive at high.
• Clipped Bands — the real glitch: two extra copies of the text (drawn by ::before and ::after from the data-text attribute) are sliced into horizontal bands with clip-path: inset() and shifted out of register, so slices of the word appear to tear loose and snap back.
• Jitter & Skew — the whole block shudders and skews in hard steps, with the color split flashing in and out. Good for a 404 or an error state.
• Flicker — a failing-neon-sign blink: the text dims and re-fires on an irregular schedule with a color bleed at the edges.

How intensity works

Intensity is the displacement, in pixels, that every layer of the effect moves. It scales the text-shadow offsets, the left offsets of the clipped band layers, and the translate distance of the jitter. As a rule of thumb, keep it near 5% of your font size — around 4px at 80px type — then push higher for a hero and lower for anything you actually expect people to read.

Motion accessibility

Rapid, high-contrast motion is a known trigger for migraines and vestibular symptoms, and a glitch loop is about as rapid and high-contrast as web type gets. Every snippet this tool generates therefore ends with a @media (prefers-reduced-motion: reduce) block that sets animation: none, so the text falls back to a clean static state for anyone whose system asks for reduced motion. Keep that block when you paste the CSS in.

How to use it

1. Enter your Text. It is written both as the element's text and into its data-text attribute, which the Clipped Bands layers read.
2. Pick a Glitch Effect, then set Font Size and Font.
3. Choose the colors: Text, Background, and the two Glitch Colors (cyan/magenta is the traditional pairing).
4. Tune Intensity and Loop Duration — a shorter loop reads as more frantic.
5. Copy the CSS into your stylesheet and the HTML into your markup.

FAQ

Why does the snippet set a background color? The Clipped Bands effect paints its two duplicate layers with a solid background so the slices mask the original text underneath. If that color doesn't match what's actually behind the element, the seams show. Set Background Color to your real page background — or keep the element's own background, which the generated CSS applies for you.

Can I use it on an existing element instead of the generated <div>? Yes. Add class="io-glitch" and a data-text attribute holding the same text. The data-text value is what the effect layers duplicate, so it must match the visible text or the tear will show the wrong characters.

Does it work on multi-line text? The effect is designed for a single line — a heading, a logotype, a 404. The clipped layers are positioned against the element box, so long wrapped paragraphs will look misaligned.

Is anything uploaded? No. The snippet is generated in your browser from the values you enter; nothing is sent to a server or stored.
