404 Block Builder

This tool creates a fully responsive, copy-paste-ready HTML 404 page with inline CSS that works in any environment.

🛠 To implement this 404 page:

• For WordPress: Add this code to your 404.php template file
• For static sites: Create a 404.html file in your root directory
• For server-side frameworks: Add to your error handling route

🧩 This HTML works perfectly in:

• WordPress (as HTML block or template)
• Static site generators (Jekyll, Hugo, etc.)
• Custom-coded websites
• Most web frameworks

💡 Pro Tip: Customize the colors and content to match your brand identity for a seamless user experience.
