That div will break the video out of the theme’s column width and stretch it full-bleed across the viewport.

A couple of notes:

• Some themes already makeresponsive; if yours does, you only need the full-width container.

• If you want to enforce a ratio (16:9), you can use a second wrapper with padding-top:56.25% trick, but in many cases the built-in responsive CSS will handle it.

• This way you don’t have to fight WordPress’s stripping of <style> or <script> — all the control is via inline style on the div.
