You have to provide at least a maintenance.html page but you can provide images, css, custom font, etc. if you want. Just write absolute paths in your html and not relative ones (so to serve image.jpg which is at the same level than your maintenance.html page you’ll write “/image.jpg” instead of “./image.jpg” or “image.jpg”).
