Internet Explorer making up CSS for BODY -

here internet explorer showing me css:

see line i've selected yeah that's not there in css. infact it's else:

/* copyright (c) 2003-2013, cksource - frederico knabben. rights reserved. licensing, see license.html or http://ckeditor.com/license */  body { /* font */ font-family: sans-serif, arial, verdana, "trebuchet ms"; font-size: 12px;  /* text color */ color: #333;  /* remove background color make transparent */ background-color: transparent !important;  margin: 20px; } 

you'll notice i'm trying make background ckeditor 10 transparent. you'll notice ie seems making $h1t up.

any ideas how can tell ie stop doing , make background transparent?

i have tried remove background style, ignores that. i've cleared cache , still no joy. can guess chrome , other browsers work fine.

you can use css reset override browser's default css http://www.cssreset.com/
