Give a smart and professional look with this creative 404 page. This error 404 page template contains a shadow effect with a company logo and links to redirect it to home page. Entierly designed with HTML5 & CSS3. This error 404 page widget template is 100% responsive and cross-browser compatible.
Version 2.0 restyles the panel over the photo — a normal, flowing layout with a soft gradient edge in place of v1's skewed, viewport-pinned panel — and adds contact.html (a working contact form), 500.html, maintenance.html (a live countdown and notify-me form) and offline.html, plus three ready-to-send HTML emails in the same design: the contact auto-reply (email-contact.html), the notify-me confirmation (email-notify.html) and a maintenance heads-up (email-maintenance-notice.html). Every form can be pointed at your own server with one attribute, and the fonts are self-hosted.
- contact.html — a working contact form: name, email and message with validation and a confirmation panel.
- 500.html — a server-error page in the same design, with Try Again and Back Home buttons. Marked noindex.
- maintenance.html — a scheduled-maintenance page: a live countdown and a notify-me email form. Marked noindex.
- offline.html — a no-connection page: a Try Again button that reloads, and a line that appears automatically when the connection comes back. Marked noindex.
- Three ready-to-send HTML emails: email-contact.html (the auto-reply)
- Connect any form to your server: add data-endpoint="https://your-site.com/api/…" and it is POSTed there. Without it every form runs as a demo (each shows a "Dem
- v1's panel was pinned with position:absolute and a skewed transform
- The two dead "#" buttons on the 404 page now go to a real destination: Back Home to "/", Contact Us to contact.html.

What’s new
v2.0Sep 2026
- contact.html — a working contact form: name, email and message with validation and a confirmation panel.
- 500.html — a server-error page in the same design, with Try Again and Back Home buttons. Marked noindex.
- maintenance.html — a scheduled-maintenance page: a live countdown and a notify-me email form. Marked noindex.
- offline.html — a no-connection page: a Try Again button that reloads, and a line that appears automatically when the connection comes back. Marked noindex.
- Three ready-to-send HTML emails: email-contact.html (the auto-reply), email-notify.html (sent by the notify-me form) and email-maintenance-notice.html (a heads-up to send before maintenance starts). Table-based and inline-styled for Gmail, Outlook and Apple Mail, no images, {{placeholders}} for your mailer.
- Connect any form to your server: add data-endpoint="https://your-site.com/api/…" and it is POSTed there. Without it every form runs as a demo (each shows a "Demo only" line — delete those lines when you go live). Details at the top of js/main.js.
- v1's panel was pinned with position:absolute and a skewed transform, with a different top/left/width percentage at every breakpoint — a fragile design that could not safely carry the new, taller pages (a contact form, a countdown) and did not verify reliably across browsers. It is now a normal, flowing panel: no skew, a soft gradient edge into the photo instead of a hard diagonal cut, left-aligned text. Checked at 320-1440px in both Chromium and Firefox, with no clipping at any width.
- The two dead "#" buttons on the 404 page now go to a real destination: Back Home to "/", Contact Us to contact.html.
- The page had two <h1>s (LOGO, the error heading) — a real accessibility bug. LOGO is now a normal, styled h2; the error heading is the page's one h1.
- Meta description added to every page; the credit line shows the current year.
- No framework in v1, none added: one small stylesheet, one dependency-free js/main.js. Roboto ships inside the page (woff2, the weights used); nothing is fetched from Google.
