| Code for link-hover text boxes | ||
| By Nicolas Höning | ||
| Usage: <a onmouseover="nhpup.popup('popup text' [, {'class': 'myclass', 'width': 300}])">a link</a> | ||
| The configuration dict with CSS class and width is optional - default is class .pup and width of 200px. | ||
| You can style the popup box via CSS, targeting its ID #pup. | ||
| You can escape " in the popup text with ". | ||
