Embedded responsive video is cropped

I embedded a Vimeo video on this page (Activate2027 | Register Now) following the instructions on this page (https://knowledge.hubspot.com/articles/kcs_article/cos-pages-editor/how-do-i-make-my-embedded-youtube-video-responsive). The video is responsive but the top and bottom of the video are cropped off. Any thoughts as to how to fix this?

Main cause of issue is that in ActivateStylesheet.css file element .hs-responsive-embed iframe has given property top:20px. Which results in cropping of video.

Option 1: To resolve this issue we can change css property top:20px; to top:0px; in css file.

Option 2: Don’t worry if you are not technical enough to change it from css file than you may add below code in page editors html.

<style>
 body .hs-responsive-embed iframe { top:0px }
</style>

Below screen shows where to add code..
