How to create google plus circle with mouseover effect?
<p>Those of you who have seen google plus may know what Im taking about...</p>

<p>Essentially my problem is this. I would like to have a circle with radius for example of some number of pixels with text in the center. On mouseover, the outline of the circle expands by whatever it was plus 5. When I mouse out, the circle gradually shrinks back to its original size. If the text in the middle of the circle is clicked then an alert box of some sort pops up.</p>

<p>What is a good way to do this and how? Does it involve div tags?</p>
