ToolTip is a script that can be used to make a tooltip immediately appear when a user mouses over an element that has a 'tip' attribute set. The ToolTip will follow the mouse for as long as the user remains over the element. All you have to do is something like this:

<p tip="Here's a tip!">Here's my paragraph.</p>

You can customize the script by assigning your own style to the tooltip as well as setting a maximum width. Here are a few examples of the script in action:

It is also possible to use this script with elements that are dynamically added to the document. You can do something like this:

var myDiv = document.createElement('div');
myDiv.onmouseover = showTip;
myDiv.onmouseout = hideTip;
myDiv.tip = "Here's my tip.";
myDiv.innerHTML = "Here's my content.";
document.appendChild(div);
