This is the default 404 error page file distributed with the nginx web server on Fedora systems. It is intended for website administrators who need to manage the user experience when a visitor encounters a missing page. A generic error page can frustrate users and lead them to leave the site; customizing this page helps retain visitors by providing helpful navigation or branding.

• Default Error Page File: The provided HTML file is located at /usr/share/nginx/html/404.html and is served automatically when nginx cannot find a requested resource.
• Direct Configuration Path: The page references the primary nginx configuration file (/etc/nginx/nginx.conf), where administrators can edit the error_page directive to point to a different custom file.
• Foundation for Customization: This file serves as a starting template. Administrators can edit its HTML and CSS to create a branded, helpful error page that aligns with their site's design and offers links back to the homepage or a search function.
• Standardized Location: Using this default file ensures consistency and simplifies setup, as it is placed in the standard directory nginx checks for error documents by default in this distribution.
