Installed Organic WordPress theme for client. But some images was not fully shown in mobile device. Client wanted to make the background responsive.

Organic theme was used inline style like below to set background image.

<div class="cms-fancybox-item clearfix" style="background-image:url(http://www.sitename.com/images/coupon.jpg);">

So I added a extra class ‘coupon’ through WPBakery Page Builder and added the following in style.css

.coupon .cms-fancybox-item{
	background-repeat:no-repeat;
	background-size:contain !important;
	background-position:center;	
}
