Hi there,
The YouTube Video Embed Block doesn’t have any controls it automatically displays the video at the original aspect ratio and fills the space available to it. You can make it smaller by doing this:
1. Select the Video Block, go to Settings > Advanced -> Additional CSS Class(es) and add: contain-video
2. Publish those changes.
3. Add this CSS to your site:
.contain-video {
max-width: 360px;
}
Change the 360px to the max-size you require.
