What is a CSS glitch effect?

A visual effect that makes text look like it's glitching—often using pseudo-elements, clip-path, and animation with offset shadows or duplicates.

Do I need to copy both HTML and CSS?

Yes. The tool outputs a small HTML snippet and the CSS. Paste the CSS into your stylesheet and use the HTML structure where you want the glitch text.

Can I customize colors and speed?

The generated snippet uses CSS variables or simple values you can edit (e.g. color, animation-duration) after copying.
