accessibility

问题 I've stuggled to find an answer to this problem, I would like to add controls to HTML5 background video, so that users can at least choose to pause the video for accessibility reasons. The built-in HTML5 "Controls" attribute work just fine but as soon as I add my CSS to put the video in the background, the controls disappear. How do I keep the controls and have the video in the background? Here is my simple HTML5 code: <div class="fullscreen-bg"> <video controls loop muted autoplay poster=

问题 I have a table with cells that the user may swipe to mark them "completed". I am trying to make this accessible using VoiceOver by implementing the accessbilityScroll method. This works fine, but I can't figure out what cell has focus when the user scrolls. I only find information on how to change focus. 回答1: Hehe, Ok. I just figured it out. There is a protocol for this.
