Question

Below is some html I found in this jquery tooltip tutorial, the contents inside of content”” show up in the tooltip using javascript. I have never seen the content propert befre, I search on W3schools.com but and google but could not find anything about it. Is this a valid property?

<a href="#" alt="Image Tooltip" rel="tooltip" content="<span>Image Title</span><br/> <img src='http://papermashup.com/demos/jquery-gallery/images/t2.png' width='120' height='120' class='tooltip-image'/> This is an example of an image tooltip with jquery, with a little bit of text.<br/> Remember you can follow me on twitter just search: ashleyford">Image Tooltip</a>

sorry If I am overlooking this, I searched but just briefly, didn’t look too much before asking this.

If you need to put custom attributes into an element, then use the html5 data- attributes.

Shamelessly copied from John Resig:

<li class="user" data-name="John Resig" data-city="Boston"
     data-lang="js" data-food="Bacon">
  <b>John says:</b> <span>Hello, how are you?</span>
</li>
