TL;DR:<\/strong> A CSS glitch effect creates the cyberpunk RGB-split look \u2014 text rendered three times in red, cyan, and white, with each layer offset slightly and animated to create a “broken display” feel. Used for hero text on cyberpunk-themed sites, gaming UIs, error states, and brand identities that want a “glitchy” aesthetic. Our free CSS glitch generator<\/a> ships 8+ presets, animation controls, and respects prefers-reduced-motion<\/code> for accessibility.<\/div>\n

The “glitch text” aesthetic peaked in the late 2010s alongside cyberpunk’s design revival \u2014 Cyberpunk 2077 marketing, gaming UIs, vaporwave Tumblr blogs, hacker-aesthetic indie sites all leaned on RGB-split text. The technique mimics a CRT display with misaligned colour channels. The CSS implementation: render the text three times \u2014 one layer in red shifted left, one in cyan shifted right, one in white at original position \u2014 then animate the offsets randomly to create the “stuttering” feel.<\/p>\n

Our CSS glitch effect generator<\/a> ships 8+ tested presets ranging from subtle (a steady RGB split with no animation) to chaotic (rapidly stuttering text with clip-path slices). All output is pure CSS with no JavaScript dependency, and includes a @media (prefers-reduced-motion)<\/code> branch that disables the animation for accessibility-sensitive users. This guide covers the technique, the accessibility considerations, and when the glitch aesthetic is the wrong choice.<\/p>\n

Glitch effect anatomy<\/h2>\n

The classic RGB-split glitch uses CSS pseudo-elements and absolute positioning:<\/p>\n

.glitch {\r\n  position: relative;\r\n  color: white;\r\n  font-weight: 700;\r\n}\r\n.glitch::before,\r\n.glitch::after {\r\n  content: attr(data-text);\r\n  position: absolute;\r\n  top: 0;\r\n  left: 0;\r\n  width: 100%;\r\n  height: 100%;\r\n}\r\n.glitch::before {\r\n  color: #ff0080;\r\n  transform: translate(-2px, 0);\r\n  mix-blend-mode: screen;\r\n  animation: glitch-1 2s infinite;\r\n}\r\n.glitch::after {\r\n  color: #00fff0;\r\n  transform: translate(2px, 0);\r\n  mix-blend-mode: screen;\r\n  animation: glitch-2 2s infinite;\r\n}\r\n@keyframes glitch-1 {\r\n  0%, 100% { transform: translate(-2px, 0); }\r\n  20% { transform: translate(-3px, 1px); }\r\n  40% { transform: translate(-1px, -1px); }\r\n}\r\n@keyframes glitch-2 {\r\n  0%, 100% { transform: translate(2px, 0); }\r\n  20% { transform: translate(3px, -1px); }\r\n  40% { transform: translate(1px, 1px); }\r\n}\r\n@media (prefers-reduced-motion: reduce) {\r\n  .glitch::before, .glitch::after { animation: none; }\r\n}<\/code><\/pre>\n
The HTML uses data-text=\"GLITCH\"<\/code> on the element and the pseudo-elements pull that via content: attr(data-text)<\/code>. This avoids duplicating text in the DOM (which would break screen readers). Result: visually three layers of text; semantically just one.<\/p>\n

How to generate a glitch effect<\/h2>\n
    \n
  1. Open the CSS glitch effect generator<\/a><\/li>\n
  2. Type the text you want to glitch (default: “GLITCH”)<\/li>\n
  3. Pick a preset (static, smooth, stuttering, slice, etc.)<\/li>\n
  4. Adjust intensity, speed, and the two RGB-split colours<\/li>\n
  5. Click Copy CSS + HTML<\/strong> for a complete drop-in component<\/li>\n<\/ol>\n
    Accessibility \u2014 glitch effects can cause harm<\/h2>\n
    Animated glitch effects can trigger problems for users with vestibular disorders, photosensitive epilepsy, and cognitive disabilities. Build them carefully:<\/p>\n
