Hi @mica123
Margins are outside of the element, as you can see on this box model example: https://www.w3schools.com/css/css_boxmodel.asp
so they don’t use the background color of the element where they were added. The color you’re seeing is coming from one of the parent elements.
Use your browser’s developer tools to find the element that has the color:

https://smartslider3.helpscoutdocs.com/article/318-chrome#css
and try to adjust it there.
If you can’t find the element, please send me a link to your site where I can see the problem! In case you don’t want to post the URL to a public forum, please send it privately at: https://smartslider3.com/contact-us/support/?ref=https://wordpress.org/support/topic/top-margin-grey-color/
Or alternatively, you could try using padding instead of margin. In this case the background “inside” the box would be used.
Thank you for the speedy reply. Yes, I identified the problem – that’s why I deleted my post. Thanks again.
