Need to make somethings similar to this. Is for captive portal.
Show up a image/video with a count down, and 10 seconds, then show up click to continue. It will need to have a good UI design. Also, need a UI login page .
You would need to work with current programmer to make that. This is for captive portal. Need to be mobile responsive.
Sample login page. You don't need to do the captive portal. You only do the design and video playing functions.
