white stripe on left side

Hello Forum,

since a few days my website shows a small white stripe (about 20px) on the left side of the bg-picture. I had nothing changed. If I remember well the stripe could be since the last Joomla update (...???...)
The current version of the site is: 3.9.20
The URL is: service-fleischmann.de
If you examine the page with "F12" you can see in the right box the value for "margin: 20" in the yellow box left sided of the border (see attachment).


But I can't find this value in any css file...

I hope that anyone can help me...

Regards - Boory

Thanks for help!
