Since that plugin has so many !important declarations, it overrides the code you add in your Theme’s CSS. So to make your custom code has the top priority, you’ll need to override it by adding in something like .footer-widgets-2 right before the code I posted above (since it’s in the Footer Widgets 2 location). Example –
.footer-widgets-2 .social-bookmarks li {
display: inline-block !important;
float: none !important;
}
You could add other classes or ID’s as well, but let’s try adding .footer-widgets-2 in front of the code I posted earlier and let me know if that works.
