After opening it, a fake "Page Not Found" interface will appear on the screen, with common "404 Not Found" and "The page you are visiting does not exist" prompts. It provides a variety of templates to choose from-classic minimalist style, creative style with illustrations, and even game-style 404. The page color matching and prompt wording can be fine-tuned, allowing the event of "hanging the website" to show a different temperament.

The entire page is statically rendered by the front end, so that no network request will be actually initiated, let alone any real pages will be lost; press F11 or Esc to exit. During the demonstration, it is recommended to first confirm that the URL in the address bar has been changed to an arbitrary scribbled link, and you can also easily turn the browser window to a gray state of "Load Failed". The more details are, the less likely it will be to be seen through.

The most common way to play is to open this fake 404 when the other person is about to visit a certain webpage, and then spread his hands and say,"Is this website dead?" It is also often used as a framing prop for "website inaccessible" in film and television dramas, or a joke point in Short Video to create Internet rollover. When used together with fake 502 or fake offline pages, you can also perform a comic drama where "there is a problem with the entire network."

What should be noted is that making such a joke on someone who is grabbing classes, tickets, or submitting homework can easily and really delay things, so it is best to use it when the other person is idle; after the joke is over, refresh the real page to make everything return to normal. By the way, you can make it clear that "that was a special effect just now", and the whole ending will be complete.

A fake 404 page is a spoof gadget that can generate a "lost page" error page with one click. It can switch between multiple 404 styles and give others the illusion that opening the page failed at any time.
