CSS Hack

CSS Hacks
Hi, i’m trying to set up content within an ID to only be displayed if you are using an old browser however I didn’t realize IE 6 for PC was an old browser or had poor CSS Support because the display: none thing not only displays in IE 6 for PC but a lot of my styles are all messed up. Any tips? I’d like to straighten this out without importing the styles…

#warning {
padding: 2px 15px 2px 20px;
font-size: 12px;
line-height: 14px;
color: #c30;
text-align: left;

#subnav > #warning {
display: none;
