404 Glitch Text
A big 404 whose digits glitch one at a time, jumping, skewing and splitting into red and cyan, above a quiet PAGE NOT FOUND line. Each digit shares one keyframe and has its own delay.
Also known as: 404 page animation css, error 404 glitch, page not found text effect.

}Customizing this snippet
- Color: set
--txt-coloron the element or a parent. Currently previewing#3b82f6. - Font size: set
--txt-size. Every other dimension is inem, so the whole thing scales together. Currently previewing40px. - Speed: change the duration on the
transitionoranimationshorthand. Staggered delays are relative, so they keep their rhythm. - Reduced motion: the rule at the end of the CSS turns the motion off for people who asked their OS for less of it. Keep it.
