The salient theme wraps embedded videos (such as YouTube) in an element which causes an issue with sizing in our plugin. To fix this, simply add the following to our plugin’s Custom JavaScript section (Customize > Misc > Custom JavaScript):
setTimeout(function(){
$('#cff .cff-item iframe').each(function(){
if( $(this).parent().hasClass('iframe-embed') ){
$(this).unwrap();
}
});
}, 3000);And add this to the Custom CSS section:
#cff iframe[src]{ opacity: 1; }
