// isHiddenWithinTree reports if an element has a non-"none" display style (inline and/or
// through the CSS cascade), which is useful in deciding whether or not to make it visible.
// It differs from the :hidden selector (jQuery.expr.pseudos.hidden) in two important ways:
// * A hidden ancestor does not force an element to be classified as hidden.
// * Being disconnected from the document does not force an element to be classified as hidden.
// These differences improve the behavior of .toggle() et al. when applied to elements that are
// detached or contained within hidden ancestors (gh-2404, gh-2863).
return function( elem, el ) {
// isHiddenWithinTree might be called from jQuery#filter function;
// in that case, element will be second argument
elem = el || elem;
// Inline style trumps all
return elem.style.display === "none" ||
elem.style.display === "" &&
// Otherwise, check computed style
// Support: Firefox <=43 - 45
// Disconnected elements can have computed display: none, so first confirm that elem is
// in the document.
