How do I check if an element is hidden in jQuery?

Explanation

 So to find an element is hidden in jQuery we have a code that is suitable for the single element, this code might be more suitable:

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

// The same works with hidden
$(element).is(":hidden");

Also to check any element or to compare one element with another selector or any jQuery object we use jQuery’s is().  So to find a match we have a method that along with the DOM elements satisfies the passed parameter. It will return true if there is a match, or else it will return false. So this is done to find an element that is hidden in jQuery.
