It is possible to toggle the visibility of an element, using the functions .hide(), .show() or .toggle()?
How would you test if an element is visible or hidden?
Since the question refers to a single element, this code might be more suitable:
// Checks css for display:[none|block], ignores visibility:[true|false]
// The same works with hidden
Same as twernt’s suggestion, but applied to a single element; and it matches the algorithm recommended in the jQuery FAQ
We use jQuery is() to check the selected element with another element, selector or any jQuery object. This method traverses along the DOM elements to find a match, which satisfies the passed parameter. It will return true if there is a match otherwise returns false.
