1、I visit the site: https://metahuman.unrealengine.com/
2、all the valid element of the whole page exist in one single vedio element
<video id="30537116488358884" autoplay="" class="PixelStreamingPlayer-remote-0-2-5 PixelStreamingPlayer-cloud-0-2-6" playsinline=""></video>
3、this vedio element can receive mouse&keyboard event normally
how did the site made it?
In my mind, h5 vedio element cann’t interact with user;
