Also, I would like to add a darker background to my Header Text
Yes its possible with custom css i give you the css kindly customize as you want.
Shadow For Image
.image-ultimate-hover-1 {-webkit-filter: drop-shadow(5px 5px 5px #222); filter: drop-shadow(5px 5px 5px #222);}
For Darker Background You can set Hover background from Admin pane and if you want at normal view kindly modify this
.image-ultimate-hover-1 .iheu-img:before {background: #0000007d;}
As like as you want to use more shortcode kindly check shortcode id where this time, it is 1 and each class has 1. So modify it if you want into another shortcode.
