I tried following all these instructions, but the result was not responsive. It seems that the caption shortcode is responsible for breaking the responsiveness because it insists that a width is included.
I’m trying to show a YouTube video with a WordPress caption. Ideally I would like to remove the controls, info and related videos from the YouTube video as well, but that may be asking too much.
Does anyone have a suggestion?
