@andrew19 if you’re using a vanilla HTML5 Video tag then you just need to add the “controls” attribute to it like so:
<video controls autoplay>
That’s the simplest solution. Otherwise you would need to use your own button element, CSS to style it/position it, and JS to play/pause the video on click.
Do you know if there’s a way to customize the black gradient behind the controls? I’ve been trying to do that with CSS but can’t seem to change anything.
I’m afraid not. You could create your own video controls and style them however you like and disable the default browser controls. But that would require a bit more work than just a couple CSS styles.
