60+ HTML 404 Templates
The 404 page is an opportunity to reinforce branding and add a memorable micro-interaction. This selection features templates that use CSS animations (e.g., parallax, smooth transitions) and SVG graphics to create unique visual effects without heavy JavaScript. Special emphasis is placed on how the HTML structure easily allows for embedding humorous or themed content that turns an error into a positive experience.
Examples

3D Rolling Cube 404 Page Animation
This surreal 404 page template features a continuous, 3D animated scene. Built entirely with HTML and CSS, the layout coordinates multiple keyframe animations to move a dimensional cube along an infinite sliding rail track. As the cube rolls 90 degrees with an elastic bounce, its pseudo-elements dynamically swap text strings between ‘4’ and ‘0’ to match the passing terrain.
See the Pen 3D Rolling Cube 404 Page Animation.

Animated 404 Face HTML, CSS & SVG
This is an Animated 404 Face SVG. It uses CSS keyframes to transform the static numbers “404” into a reactive, smiling face. Its function is to provide an engaging, lightweight fallback state for broken links, softening user frustration through characterful micro-interactions.
