Inserting button problem.

On my site i am trying to add 3 buttons and am succesful at doing so. The problem is is that one of the buttons is being placed at the top of the page and is not able to be moved. here is the code for it:

<p><strong style="FONT-SIZE: 14px">3&nbsp;Valley Locations To Serve Your Fitness Needs:</strong> </p>
<div id="PHX" class="addressBox"><strong style="PADDING-BOTTOM: 1px; PADDING-RIGHT: 1px; PADDING-TOP: 1px"></strong></div>
<div id="PEO" class="addressBox"><strong style="PADDING-BOTTOM: 1px; PADDING-RIGHT: 1px; PADDING-TOP: 1px"></strong></div>
<div id="303" class="addressBox"><strong style="PADDING-BOTTOM: 1px; PADDING-RIGHT: 1px; PADDING-TOP: 1px"></strong></div>

The bottom box is going up to the top of page below the fitness needs line. Any thoughts
