White Space on right side on Mobile Devices

Hi there,

first try changing Customizer > General > Structure to Flexbox.
This should eliminate an box-sizing overflow which happens when elements have a width and padding value defined.

If that doesn't resolve the issue, leave it enabled and let us know so we can pin down the issue.

Thank you very much for the quick answer.

Unfortunately the problem is not solved yet.

I have already removed all blocks in the content (incl. Boxzilla) temporarily, even without success.

Hmmm... one of the elements that is being displayed using JS is breaking the layout.
Try adding this CSS to resolve that:

html {
    overflow-x: hidden;
}

solved the problem the hard way ;)

Thanks

Glad to hear that
