CSS Glitch Text Effect Generator – Online Copy Keyframes

A CSS glitch text effect simulates digital distortion or signal interference using pure CSS — no images or JavaScript required. It typically combines text-shadow layers with different colors (mimicking RGB channel separation), @keyframes animations for jittery movement, and sometimes skew transforms or clip-path slices to create a "broken screen" aesthetic popular in cyberpunk and vaporwave design.

@keyframes define animation stages at percentage points (0%, 50%, 100%, etc.). For glitch effects, most frames keep the text stable, while specific frames (e.g., 12%, 34%, 78%) introduce sudden text-shadow offsets, transform skews, and opacity flickers. The sharp transitions between normal and distorted states create the signature "glitch" look. Use animation: glitch-name duration timing-function iteration-count; to apply it.

Yes! CSS glitch effects work on any modern browser (Chrome, Firefox, Safari, Edge). They are pure CSS, so there's no JavaScript dependency for the animation itself. However, use them sparingly — too much glitch animation can be distracting and may impact accessibility. Consider adding prefers-reduced-motion media queries to disable animations for users with motion sensitivity.

Generally yes. text-shadow and transform animations are GPU-accelerated and don't trigger layout recalculations. However, excessive text-shadow layers (5+) with large blur radii can strain rendering on low-power devices. The keyframes generated by this tool use 2–4 shadow layers with small offsets, striking a balance between visual impact and performance. For production, always test on target devices.

CSS glitch effects using @keyframes, text-shadow, and transform are supported in all modern browsers: Chrome 43+, Firefox 16+, Safari 9+, and Edge 12+. CSS clip-path (used in some advanced glitch styles) has slightly narrower support but still covers 97%+ of global users. For IE11, glitch effects degrade gracefully — the text remains readable without animation.

Use the color pickers above to choose your three channel colors. The classic cyberpunk look uses magenta (#ff0055), cyan (#00ffff), and blue/purple — but you can match any brand palette. The colors are used in text-shadow layers that offset in different directions during animation frames, creating the RGB split (chromatic aberration) effect. Copy the generated code after adjusting colors to your liking.

Absolutely! Change the CSS selector from .glitch-text to .glitch-text:hover in the generated code. This way the text stays normal until the user hovers over it. You can also use :focus-within for accessibility or add a CSS class toggle via JavaScript for click-triggered glitches. The keyframes remain the same — only the animation application rule changes.

Text-shadow glitch (used by this tool) offsets colored shadow layers for an RGB split look — it's simple, performant, and widely supported. Clip-path glitch uses clip-path: inset() on pseudo-elements to slice and offset parts of the text, creating a more aggressive "screen tear" effect. Advanced implementations combine both techniques. This generator focuses on text-shadow keyframes for maximum compatibility and ease of use.
