How to get rid off the white space above and below video

Hi there,

does the issue persist if you disable Autoptimize ?

If it does try adding this CSS:

.wp-block-embed iframe {
    height: auto;
}

I have disabled Autoptimize, but the issue still persists.

If you remove the Video Block, publish those changes and exit the editor.
Then re-edit the page and add the Video back in to the site.

I wonder if the recent WP updates messed with the core blocks embed CSS....

yes, unfortunately the issue persists.

I have now added this CSS and the white space disappered:

.wp-block-embed iframe {
    height: auto;
}

But now the video is very small on desktop and tablet view.

Please check and advise.

Thank you

What if we make it mobile only?

@media (max-width: 768px) {
    .wp-block-embed iframe {
        height: auto;
    }
}

yes, helpful. Thank you, Leo

Will this issue be fixed in one of the next updates?

That looks like a CSS issue from WP core but we will take a closer look.
