Can't center responsive video
Maybe I'm missing something obvious here. Compare:
I've tried every CSS trick I know, applying text-align: center; and margin: 0 auto; to both the wrapping div and to the myElement div, complete with !important attributes. Nothing works. Something in the JW script itself is stubbornly overriding my CSS.
If you tinker with the developer tools, you will be fooled into thinking you've cracked the problem by applying margin: 0 auto to myElement. But that doesn't actually work when the player loads - it's executing some kind of reset that clobbers it again.
