CssClassSet classes

The set of CSS classes applied to this element.

This set makes it easy to add, remove or toggle the classes applied to this element.

    element.classes.add('selected');
    element.classes.toggle('isOnline');
    element.classes.remove('selected');

## Implementation

    CssClassSet get classes => new _ElementCssClassSet(this);

void classes= (Iterable<String> value)

## Implementation

    set classes(Iterable<String> value) {
      // TODO(sra): Do this without reading the classes in clear() and addAll(),
      // or writing the classes in clear().
      CssClassSet classSet = classes;
      classSet.clear();
      classSet.addAll(value);
    }
