Does this make sense?
HERE'S THE CODE FOR THE "LOGIN" DIV IN THE INCLUDED FILE "HEADER.HTML":
<span style="color:#88e2b5; font-size:16px; font-style:italic; padding: 0 3px 0 0">Page1</span>
<form method="post" accept-charset="utf-8" action="https://www.accountantsoffice.com/AOAdmin/AOLogin.aspx?firmcode=capit7070">
<input type="submit" name="button1" value="client login" style="color:green" />
