Designer's Thoughts:

Considering that 404 pages are only visited by 1-2 out of every 1000 users, there is no need for special confusing visuals or long explanations. All it takes is a creative detail, a short explanation and a 'back to home' button.

Design Online is an online design magazine journal. As part of the ui design of the process, I took advantage of the idea of ​​nested circles, which Design Online often uses, as a dart board. Arrows that do not go to the target are symbols of 404 errors. In addition, I placed a button to briefly explain to the user and return to the main page.
