Fix Contact and button color on website

I recently moved the website [login to view URL] to Hostgator. The contact form is not working [login to view URL] and the navigation buttons when selected wash out instead of changing color. Here is a snippet of the code <form action="cgi-bin/[login to view URL]" id="contactform" method="post"> <p><label>First Name:</label> <input name="first_name" type="text" value="" /></p> <p><label>Last Name:</label> <input name="last_name" type="text" value="" /></p> <p><label>Email:</label> <input name="email" type="text" value="" /></p> <p><label>Subject:</label> <input name="subject" type="text" value="" /></p> <p><label>Message:</label><textarea cols="50" name="message" rows="5"></textarea></p> <p style="text-align: center;"><input id="contactsubmit" type="submit" value="Contact Us" /></p> </form> </article> </div> <div><img class="module image" src="/images/[login to view URL]" /></div> <!-- InstanceEndEditable --></div> </div>
