Change aspect ratio of single video

Hi all,

Does anyone know how to change the aspect ratio of just one video block?

I've managed to change the ratio of all videos with this code:

.sqs-native-video .native-video-player {

    padding-top: 30% !important;

}

but when I try to direct it at one block (I used #block-83411e5704c79262fddc) it just changes the actual padding and moves the video down the page.

Can anyone point out what I'm doing wrong?!

I'm trying to change the top video on the page highriselandscapes.org/exhibition-copy to double-widescreen.

First screenshot is how it looks now; second one is how I want it to look; third is how the other video on the page goes wrong with the code I tried. 

Can you share your website URL?

Try this Custom CSS:

section[data-section-id="63909e34884caf2f0c7b2a83"] {
  .sqs-native-video .native-video-player {
    padding-top: 30%;
  }
}

Let me know if that works!

Yep, that's perfect! Thanks so much
