Replace Lines 79 - 90 of your HTML code with this:
<div class="interior-body-full"> <h1>Presidio Cisco Profile</h1> <table> <tr> <td> <img src="images/Quadrant1.png" width="400" height="400" /></td> <td><img src="images/Quadrant2.png" width="400" height="400" /></td></tr> <tr> <td> <img src="images/Quadrant1.png" width="400" height="400" /></td> <td><img src="images/Quadrant4.png" width="400" height="80" border="0" /> <br /> <iframe width="400" height="315" src="http://www.youtube.com/embed/RtjEz8e_XbI?list=UUFiRYYo7EyMpX-YEj0Kholg&hl=en_US" frameborder="0" allowfullscreen></iframe></td> </tr> </table> |
Just a quick suggestion - while I do understand you mentioned you're still a beginner, you should consider learning CSS instead of tables.
