Question

I just posted on here with a problem that I am having with div alignment. My original question was answered but now I am having yet another issue. Link to what I am trying to do: Click here for the images (Nothing harmful by clicking on link) and by the way, this is NOT for homework. The top image (Something I created in Fireworks) on the link is the layout I was first trying to do (I got that issue resolved), but now I am trying to add a sitename div and as you see in the second picture, it is creating issues with the right div.

I am really off my game yesterday and today and making these simple stupid mistakes. I just need another pair of eyes to see what my issues are.
Thanks.

CSS:

#header {
width:750px;
height:341px;
margin-left:25px;
display:block;
}
#tableleft {
float: left;
width: 128px;
margin-left:10px;
margin-right: 5px;
margin-top:10px;
}
#Sitename {
text-align: center;
white-space: normal;
display: table;
float: left;
width: 400px;
height:40px;
margin-top:10px;
margin-left:25px;
font-family: Verdana, Arial, Helvetica, sans-serif;
font-size: 20px;

}
#tablecenter {
margin-left:20px;
float: left;
width: 410px;
margin-bottom:5px;
margin-top:30px;
}
#tableright {
float: right;
width: 128px;
margin-left: 20x;
margin-right:10px;
margin-top:10px;
margin-bottom:5px;
}

  <div id="tablecenter">

  </div>
  <div id="tableright">
    <p align="center"><img src="images/SmWhitepic.jpg" alt="" width="118" height="87"  /></p>
    <p>&nbsp;</p>
    <p align="center"><img src="images/SmWhitepic.jpg" alt="" width="118" height="87" /></p>
    <p>&nbsp;</p>
    <p align="center"><img src="images/SmWhitepic.jpg" alt="" width="118" height="87" /></p>
  </div>
</div>

Answer 1

You could nest <div id="Sitename">Content for id "Sitename" Goes Here</div> within <div id="tablecenter"> but remove the float: left; and let it display: block;
