12. Styling XForms

In the W3C XForms specification, pseudo-classes (http://www.w3.org/TR/2003/REC-xforms-20031014/sliceF.html#id2644859) can be used to select elements based on XForms criteria.  This release of the Mozilla XForms product does not support pseudo-classes, but instead uses attributes.  This will be fixed for the final release.  For example, to give all inputs a red background if they are invalid, the following CSS is used:

@namespace xf url("http://www.w3.org/2002/xforms");
xf|*[invalid] input {
  background-color: red;
}

Supported attributes in this release are valid, invalid, enabled, disabled, required, optional, read-write and read-only.
