CSS Rendering Problem

I have a difference between the form in the IDE and the rendered form. The body of the form is centered in the page but is not as wide as the graphic at the top. The graphic is 800px wide but the body seems to render to 700px. The attached PDF file shows both pages. The CSS file is also attached. The original version was for 700px wide and was changed to 800px wide. I changed all the width entries to reflect the wider page. That is when the problem occurred. How do I find what was left unchanged? I have searched the entire project for 700px. Any suggestions would be greatly appreciated. TLC-IDE-vs-Render.pdf TLC.css
