Youtube embeds adding black bars depending on browser window width

Hello

The following page adds black bars inside of the youtube video during playback depending on what width/height the browser window is currently.

Is there a way to modify the css or something like this to make the video size static or shift in a way that will not introduce these black bars into the video frame?

Hello There,

Thank you for posting in! Regretfully the black bars is coming from Youtube itself. If you want to get rid of this, please refer to these related threads:
