I’m trying to fix a table and make it look better (I describe the issue better in the screen shot below).
this is a screen shot of what’s going on and what I would like to happen:

What do I change in my style sheet?
the css file is located at rankingclimber.com/css/style.css (the footer part is clearly marked) and the signup part is clearly marked
The sign up page is located at http://www.rankingclimber.com/signup.php
here’s the code for the footer file: rankingclimber.com/footer.php and the footer is called on the main page: rankingclimber.com/signup.php
To fix the placement of the line, move
<div class="form_bt"></div>to just after the closing tag of<div class="form_tp">.To fix the “Create Account” button not being inside the form, from
<div class="chkp3">, removefloat: leftandmargin-bottom: 20px. Then, to<a class="btn1">, addmargin-top: 20px.To fix the footer, move
<div id="footer">to just after the closing tag for<div id="wrapper">.Tested in Firefox only, with Firebug.
Another answer pointed out you have missing close tags. In that case, my answer might not be very useful as the problems could have been caused purely by those missing tags.
Fix the missing close tags, and then see what your page is like before following any of the steps I posted.
