Error pages are web pages displayed when a user encounters a problem while trying to access a website. Common types include the 404 Error Page, which indicates that the requested page could not be found, and the 500 Error Page, which signals a server issue. These pages help inform users about the problem and often provide options to navigate back to the main site or search for other content. Designing effective error pages is important for user experience. A well-crafted error page can guide users back to functional areas of the site, reducing frustration. Many websites use creative designs or humor to soften the impact of the error and keep users engaged.
