site not working properly in IE

Hi ,
pease have a look at http://classifiedspak.com[^].
Im working on it. It is not working fine in Internet explorer 9, but its works fine in google chrome.
I have used simple HTML and nothing HTML5 related. I also used old CSS and some places I used CSS3 which are working fine in IE and Chrome.
I don't know what the problem is and need someone to help.

---------
PROBLEMS:
- In IE : -Unable to see logo in top left corner.
-Unable to see headings like Quick links , Welcome to classifiedspak and other headings and other headings

THESE ARE VISIBLE IN CHROME but not in IE 9.

following is the css :


.logo { height:96px; padding:0; margin:0 auto;}
h1 { margin:0; padding:30px 0 0 20px; color:#636363; font:bold 38px/1.2em Arial, Helvetica, sans-serif; letter-spacing:-2px;}
h1 a, h1 a:hover { color:#636363; text-decoration:none;}
h1 span { color:#78bbe6;}
h1 small { padding:0 10px; font:normal 12px/1.2em Arial, Helvetica, sans-serif; letter-spacing:normal;}
h2 { font:normal 24px Arial, Helvetica, sans-serif; padding:8px 0; margin:0; color:#595959;}
