> If you create custom controls and then enable native captions, unless you're Crunchyroll, your controls probably take up space at the bottom of the display area. This is the same area where the captions appear, which means that when the controls are displayed, they may overlay the captions. (Please don't hide the captions altogether! Unfortunately, I've seen this on some players that shall remain nameless.)<p>My previous job was doing digital distribution of advertising content. There's a thing called 'safe area'<p><a href="https://en.wikipedia.org/wiki/Safe_area_(television)" rel="nofollow">https://en.wikipedia.org/wiki/Safe_area_(television)</a><p>Where all text/legal content must be inside this safe area, we create a new player and got alot of upset customers because the controls overlaid on the video, this was especially annoying for them when they paused the video as the controls would stay until you unpause.<p>It wasn't until I was fixing this that I realised how annoying it is that the controls overlay on top of captions. Youtube does well by pusing the captions up if the controls are overlaid. But all streaming services put the controls over the top which annoys the hell out of me.<p>Edit: As a side note Unilever i believe it is, is doing a huge push for accessibility in Europe to support sign language, subtitles, closed captions, (and another one i cannot think of) in all their advertising. I think its a really good initiative.
