Invalid CSS

[Spug]

When clicking the CSS button at the bottom of the Ubuntu page, the CSS is deemed invalid with the following errors:

"Errors
URI : http://www.ubuntulinux.org/plone.css
Line: 719 Context : .portalMessage , .system-message , #error-handling

Invalid number : background-position Too many values or values are not recognized : 5px center
URI : http://www.ubuntulinux.org/ploneCustom.css
Line: 186 Context : tr.lit

Invalid number : border Too many values or values are not recognized : 2px solid orange"

However, when using the CSS Validator with the URI of the website (just http://www.ubuntulinux.org, not the stylesheets themselves), it appears valid (http://jigsaw.w3.org/css-validator/validator?uri=http%3A%2F%2Fwww.ubuntulinux.org%2F&usermedium=all). Strange.

Have you told the official Ubuntu web site staff about this? The forums here have a different set of web staff and have no control over the Ubuntu site.
