jquery check if all elements hidden

JavaScript
// Checks CSS content for display:[none|block], ignores visibility:[true|false]
$(element).is(":visible");

// The same works with hidden
$(element).is(":hidden");// Checks css for display:[none|block], ignores visibility:[true|false]
$(element).is(":hidden"); 
if($('#list-team-single-container').children(':visible').length == 0) {
   // action when all are hidden
}
