Error Pages – 8 Free 404 & 500 Templates
Error Pages is a pack of eight ready-to-ship error pages: five 404s, two 500s, and a 503 maintenance page with a live countdown. Each design is a single self-contained HTML file — the CSS (and the illustrations, which are pure CSS) is inline, so the page renders even when the rest of your server is on fire. That’s the point of an error page.
What’s included
- 404s — minimal giant-type, lost-in-space (CSS moon + stars), helpful-with-search, glitch animation, neobrutalist
- 500s — terminal-style with log excerpt, friendly with a blinking CSS face
- 503 — maintenance page with spinning gear and live countdown
- No images, no fonts, no dependencies — every page is one file

How to use
Point your server’s error directive at the file — nginx error_page 404 /errors/404.html;, Apache ErrorDocument, or your framework’s error route. Copy and colors live at the top of each file. Full write-ups on the error page templates page.
