How does the CSS glitch effect work?
It uses two duplicate copies of the text (typically via `::before` and `::after` pseudo-elements with a `data-text` attribute), each colored differently (often cyan and magenta) and offset slightly. Animations randomly shift the offsets and clip-paths to create the displaced, distorted look reminiscent of CRT or VHS interference. The original text underneath stays selectable, and the duplicates are decorative.
How do I keep the text accessible during a glitch?
Make sure the real text remains readable and is the actual DOM content; the glitch should be purely visual via pseudo-elements. Add `aria-hidden="true"` (or use `content: attr(data-text)`) on the duplicate layers so screen readers don't announce the text three times. Avoid running the glitch indefinitely; respect `prefers-reduced-motion: reduce` to disable it for users sensitive to motion.
Why is my glitch effect causing performance issues?
Glitch animations often shift `clip-path` or `text-shadow` rapidly, which can be paint-heavy. Limit the effect to short bursts (a few seconds on hover) rather than running it constantly across a full page of text. Animate `transform` instead of `left`/`top` for displaced layers, and avoid filter effects on top of glitch animations because compounded effects multiply paint cost.
How do I use `data-text` for duplicated layers?
Add `data-text="Your text"` to the element, then in CSS use `content: attr(data-text);` inside `::before` and `::after`. This duplicates the text without writing it three times in HTML and stays in sync if you change the text. Bonus: a single source of truth means screen readers, search engines, and copy-paste all use the original text, while the visual layers are pseudo-element decoration.
Can I trigger the glitch on hover or focus only?
Yes. Define the keyframes globally but apply the animation only inside `:hover` and `:focus-visible` selectors. Without the trigger state, no animation runs, so the text sits perfectly still. This pattern is great for headlines, CTAs, and 404 pages where you want the effect to feel rewarding rather than overwhelming. Add a small delay before triggering to make it feel less twitchy.
What sizes and fonts work best for glitch?
Bold, condensed, monospaced, or display fonts read most clearly through the chromatic aberration of a glitch effect. Light or thin weights tend to disappear under the duplicated layers. Larger sizes (32px and up) are easier on the eyes and let the offset clearly read as glitchy rather than blurry. Keep glitch text short (a single word or phrase) for maximum impact.
