Styling an embed element; responsive styling for a youtube embed

I’ve embedded the shareable code from YouTube to embed a video on a Webflow blog page. I added an Embed element from Webflow and pasted in the code from youtube. The code snippet from Youtube styles the live element with rigid pixel widths that look good on desktop and tablet but are wider than most mobile portrait breakpoints.

How would I go about styling the element, for styling my Embed class does not yield anything but a wider-looking div, while the youtube embed’s resolution stays the same. It seems youtube’s code is over-riding the parent Embed element.

Any info on this would be cherished.
