Solution for this topic

We are using an icon box slider and this is not appearing cleaning on the mobile view.  There is lot of empty space as in the image attached.

I can see the Icon box slider is displaying fine without any empty space as shown in the attached screenshot.

Please test it clearing your browser cache.

Also the about us section is not getting the side spacing as in the desktop version. Kindly advise.

It seems happening because you have removed the padding of the About Us section row on mobile causing the issue.

To resolve the issue, either remove that padding or add the following CSS code in the Custom CSS code option of your theme on the below path.

Admin Area -> Appearance -> Theme Settings -> Custom Code -> CSS Code

#content div#aboutus {
    padding-top: 110px !important;
    padding-right: 20px !important;
    padding-bottom: 20px !important;
    padding-left: 30px !important;
}
