I'm experimenting with CSS3, and for some reason, it keeps returning 'Parse Error [empty string].

I suspected it might be because I used proprietary tags frequently, but I tried commenting them out, and it still didn't validate.

Below is my CSS -- I commented all the proprietary tags out.





body {
/* Body is for the entire screen. */
display:block;
font-size:100%;
background-color:#fff;
background-image: url(graphics/placeholder.jpg);
background-repeat: repeat;
background-attachment:fixed;
}

#boundary {
/* Boundary lies in body, defines the edges of where
everything may lie in */
display:block;
position:relative;
overflow:hidden;
z-index:2;

width:45em;
margin-left:auto;
margin-right:auto;
margin-top:3em;
margin-bottom:3em;

border: 0.15em solid #aaa;

/* Code for rounded corners */
/* Currently no support for IE < 9 */
border-radius: 1em;
/*-moz-border-radius: 1em;*/
/* End of code for rounded corners */

padding:1em;
}

.opaque {
position:absolute;
z-index:1;

left:0;
top:0;
width:100%;
height:999em; /* For IE6 (Add 'oveflow:hidden' to parent) */
background: #fff;
/*-ms-filler:"progid:DXImageTransform.Microsoft.Alpha(Opacity=75)";
filter: alpha(opacity=75);
-moz-opacity:0.75;
-khtml-opacity:0.75;*/
opacity:0.75;

/* Code for rounded corners */
/* Currently no support for IE < 9 */
border-radius: 1em;

/* End of code for rounded corners */
}

Apparently, the border-radius throwing a Parse Error [empty string] is a bug in the W3C CSS validator. See http://www.w3.org/Bugs/Public/show_bug.cgi?id=11975 .

The validator will not validate vendor prefixes either as they are not part of the CSS Specification.
