How to create a CSS text glitch effect

  1. 01

    Type the preview text

    Enter 1–32 characters in Preview text — the counter beside the label tracks the length. Short, wide words read best once the layers start splitting.

  2. 02

    Set the three colors

    Text color paints the base layer, while Cyan channel and Red channel are the offset replicas that produce the chromatic fringe. Channels near pure cyan and red give the classic chromatic look; muted channels produce a subtler, more modern split.

  3. 03

    Tune the glitch motion

    Layer offset (1–12 px) sets how far the replicas drift, and Cycle duration (0.2–3 s) sets the loop speed. The preview stages all three layers live.

  4. 04

    Understand the three layers

    The base element keeps your Text color, while the cyan replica is clipped to the top of the line and the red one to the bottom. Each replica runs a steps(2, end) animation — hard jumps instead of smooth slides — which is what makes the glitch feel like signal interference.

  5. 05

    Copy the glitch CSS

    Press Copy CSS or Download .css to save toolars-text-glitch.css. A prefers-reduced-motion block ships in the export and keeps a static fringe for motion-sensitive visitors. The output panel shows the live byte count, and both actions stay disabled while the text fails validation.

  6. 06

    Add the data-text attribute

    The replicas read their content from attr(data-text), so your element needs a data-text attribute identical to its visible text. When the copy changes later, update both — the attribute is what the cyan and red layers actually paint. The attribute lives on the same element as the class, so the whole effect stays one tag.

What CSS Text Glitch Effect Generator actually does

A stream overlay wants a title that crackles, a 404 page needs just enough menace, a conference splash screen is going for retro-terminal energy. Glitch type is easy to overdo, which is why the offset and duration stay bounded — and because the effect is composed in this tab, an unreleased wordmark never leaves the machine while it is being stress-tested. Short words at large sizes carry the effect best, so test the real headline rather than placeholder copy. The exported keyframes keep the exact offset and cadence you settled on.

Common questions

What markup does the effect need?
An element with the .glitch class and a data-text attribute identical to its text content. The ::before and ::after replicas are painted from that attribute, then clipped to the top and bottom halves of the line.
What are the text limits?
Preview text accepts 1 to 32 characters, with a live counter beside the field. Empty text or anything past the limit fails validation and shows the CHECK VALUES status until it is fixed.
How does it behave for reduced-motion users?
The export includes a prefers-reduced-motion block that stops both animations and drops the replicas to 45% opacity, leaving a static chromatic fringe instead of a moving one. The base text is untouched either way, so the message stays readable in both modes.
Why does the animation jump instead of gliding?
Both replica animations use steps(2, end), which snaps the transform between discrete positions instead of interpolating smoothly. That hard stepping is the signature of signal-interference aesthetics; Layer offset sets how far each jump travels.
What offset and duration values work well?
Offsets of 1–3 px with a cycle near one second read as subtle static and suit headings that must stay legible. Push toward 8–12 px with a faster cycle only for short decorative words; the 4 px, 0.85 s defaults sit safely in between.
Is the text I type sent anywhere?
No. The effect renders locally in the current browser tab, no account is needed, and the text never enters storage, logs, or the network. Press Reset to restore the default sample.
