Having an issue with how text is displayed

I recently modified our main website template and I've apparently done something to impact how normal text is displayed on our website www.detailandscale.com.  In Dreamweaver the text on our index.html page is in normal format (first screenshoot) but since I modified the site template the page displays the text in bold italic format (second screenshot).

Any help on how to fix this would be greatly appreciated.
