Ajax add to cart ( confirming product added)screen problem for mobile

[bizpromo]

Hi there, i recently installed a theme and theres problem with once we add to cart any product, a new window opens on which i think is ajax add to cart. It confirms that product is added to cart. 

The problem is it's quite big for mobile screen and the cross (X) but does not show neither continue shopping but its perfectly fine for desktop. 

 

Is there any way to fix this issue? 

 

Thanks

The width of your ajax cart block might be in pixels (i.e. width: 900px for example), try replacing it with width: 100%;
