With .overflown() you can query a dom element and find out if it is being overflown, meaning if any of its children is overflowing the parent.
This might for instance be useful for navigation-menues where you'd like to display a hamburger-button or alike if all navigation-entries wouldn't fit in the container (and you don't want to linewrap your navigation-menue).
if ( $(".nav").overflown(direction) ){
$(".nav").addClass("overflown");
}
Where direction is optional and can either be left out or be "x" or "y" to limit to the x- or y-axis. So if you'd like to specifically find out if an element is being overflown vertically, you'd use .overflown("y"), otherwise just use .overflown()
To use jquery.overflown, jQuery 1.7 or newer ist required and you'd include it in your document, something like this:
// load jQuery first
<script src="https://code.jquery.com/jquery-1.7.2.min.js"></script>
// then load the .overflown() plugin
<script src="jquery.overflown.js"></script>
