Change background color of icon list

I have asked this question before and got som CSS code to change the background color, but the CSS isn’t working now when I’m trying to change the color of a new website! Could the reason be the latest update of WP and Enfold?

This is the code:

/* Color icon list /*
.alternate_color .avia-icon-list .iconlist_icon {
background-color: #2952a1 !important;
}

#footer .iconlist_icon {
background-color: red !important;
}
