It is important, as designers, to make sure we are design for the whole user experience—including when things go wrong. This is where 404 error pages come in. If someone mistypes a URL within your domain, the error page is displayed. If you don’t have a custom error page, the browser supplies an unuseful generic one. Your challenge today is to choose one of your completed website projects (not your menu boards) to implement a 404 error page for. Remember that a good error page should be consistent with the brand.
