CSS errors

This is on edge (r9365).

One CSS error is in the inline CSS stylesheet in e.g. https://bugs.edge.launchpad.net/launchpadlib/+bug/325367:

      <style type="text/css">
        /* A page-specific fix for inline text are editing to line up box. */
        #edit-description .yui-ieditor-input { top: 0; }
        /* Align the 'add comment' link to the right of the comment box. */
        #add-comment-form textarea { width: 100%; max-width=60em;}
        #add-comment-form { max-width: 60em; padding-bottom: 4em; }
        #add-comment-form .actions {float: right;}
      </style>

There is one "=" instead ":" in one CSS declaration.

An other error is in https://edge.launchpad.net/+icing/rev9365/lazr/build/choiceedit/assets/choiceedit-core.css:
     .yui-ichoicelist #yui-pretty-overlay-modal h2 {/
The "/" doesn't belong there.

Firefox complains about many more errors in the CSS files. Some seem to be missing newlines (https://edge.launchpad.net/+icing/rev9365/+style-slimmer.css or https://edge.launchpad.net/+icing/rev9365/lazr/build/autocomplete/assets/skins/sam/autocomplete.css) causing parse errors. It would be probably a good idea to check them all with a validator.
