Error

This css validator is great, Thanks a lot!!! But, I have found some very
little error...
When I use "filter" or "-ms-filter" property for opacity it shows that its
an error in parsing

Code:


> div#shShutter {
>     opacity: 0.8;
>     filter: alpha(opacity=80);
>     -ms-filter:"progid:DXImageTransform.Microsoft.Alpha(Opacity=80)";
> }
>

It shows last two options as error:

3     div#shShutter     Parse Error opacity=80)
> 4     div#shShutter     Property -ms-filter doesn't exist :
> "progid:DXImageTransform.Microsoft.Alpha(Opacity=80)"
> "progid:DXImageTransform.Microsoft.Alpha(Opacity=80)"
>

First as parse error, second as not existing property... I'd be glad if you
fix first error (Parse Error opacity=80), "-ms-filter" is not so need it's
only for IE8 and he shows opacity without it.(using filter:
alpha(opacity=80);) But "filter: alpha(opacity=80);" is sole css way of
implementation of opacity in IE 5-7. Thanks one more time and I'd be glad if
you'll fix this.
Good-bye and have a nice day.

P.S. Almost forgotten here is example: Site I
validated.<http://jigsaw.w3.org/css-validator/validator?uri=http%3A%2F%2Finterviewer.com.ua&profile=css3&usermedium=all&warning=0&lang=en>Site
is on Wordpress and error comes from Nextgen-galeryplug-in. Background
shutter is partly transparent.
