Quick Tip: Adding a 404 Not Found Page to your Static Site

A 404: Not Found page is a pretty standard thing on the web. It’s particularly useful when someone shares a broken or mistyped link. You don’t need dynamic middleware to do this, it’s pretty easy to add to a statically generated site. There are a few options, depending on your web host:

But first let’s make our 404.html template:

---
title: Oops! Not Found
permalink: 404.html
---

<!DOCTYPE html>
<html lang="en">
	<head>
		<meta charset="utf-8" />
		<meta name="viewport" content="width=device-width, initial-scale=1.0" />
		<title>{{ title }}</title>
	</head>
	<body>
		<h1>{{ title }}</h1>
		<p>
			This is where you should tell the user how to find their content. Maybe on
			the <a href="/">home page?</a>
		</p>
	</body>
</html>

Eleventy will output this template to 404.html.

There is no step two if you’re using one of the following hosts (a 404.html file in your output directory is all you need):

Netlify even has lovely multi-language 404 page support too using Redirects.

.htaccess

Jump to section titled: .htaccess

For other hosts, if you use .htaccess for configuration you can use ErrorDocument. Make sure your root directory matches here!

ErrorDocument 404 /404.html

With --serve

If you’re using the new Eleventy Dev Server Added in v2.0.0, the 404.html convention is now provided to you for free!
