the form was created to have a width of 820px, which is larger than the article box.
the padding and width settings for the div div element:
padding: 5px 5%;
width: 90%;
are causing some of the problem, also the form css:
form.Cool_Default {
color: #B6B6B6;
font-family: Arial,Helvetica,sans-serif;
font-size: 11pt;
margin: 0;
padding: 0;
width: 820px;
}
is setting the form width.
