CSS Validation Issue

Hello all,
I'm in the process of finishing up my site. I'm having a heck of a time validating my css. I've validated the html. But I can't seem to wrap my head around the CSS portion of it. So I come to you fine people of the codingforums.com forum to help me out.

Here's the link to the CSS validation output.

Or just look at the output:
URI : http://concentricconcepts.com/components/com_jomcomment/style.css
159 #bb_main > div Value Error : display -moz-inline-block is not a display value : -moz-inline-block

238 .postresponse, .viewresponses, div#trackback_title Property font-stretch doesn't exist : normal
266 .commentinfo cite Value Error : font-size-adjust Property font-size-adjust doesn't exist : none
267 .commentinfo cite Property font-stretch doesn't exist : normal
299 #jc_commentForm .submitbutton Value Error : font-size-adjust Property font-size-adjust doesn't exist : none
300 #jc_commentForm .submitbutton Property font-stretch doesn't exist : normal

As far as I can tell, the CSS appears valid.. Perhaps there is a rule I am not yet aware of.

What has two thumbs and is completely befuddled by this issue??? This guy!

Thanks for your help.

Most of it is valid but you need to validate with the CSS 2.1 profile. As for the invalid stuff. This is invalid
display: -moz-inline-block
That value is a mozilla only value. display is fine but -moz-inline-block is not.

Hey there,
Thanks for the reply, getting rid of the css that contained -moz did the trick and Firefox was no worse for wear either...
