Hello,

Do you have any content in main page? If so, it is not possible to disable scrolling. If you don’t have, then you can set up a smaller content height and that will disable scrolling.
If you need help with it, send us your site’s url so we can suggest the right css to edit.

Best regards!

Hello,

Sorry for the late reply.
Please add this code into your custom css box:

.home #content {
    display: none;
}

Merry Christmas and Happy New Year!
