Turyn, Michael commented on XAP-344:
------------------------------------
Widget styling may depend on more than one html dom node's styling---for
example, we might want a header to be grey with a solid black border, the
content panel to be inset and rgb(255,255,240), ahd the enclosing node
(rootDomNode in our parlance) to have a ridged border.
I would suggest that <em>eventually</em> we go to a more complicated system
that will map to named nodes in the widget, so that we can apply (e.g.):
myWidget-footerMouseOver
myWidget-clientMouseOver
myWidgetMouseOver
...where the last still applies to the enclosing dom node.
Eventually; for now let's don't over-complicate.

>
> Right now there is no good way to assign custom classes to widgets. I propose:
> 1. All xal elements should support the class attribute which is a
> space-separated list of classes.
> 2. For each entry in the attribute we should assign that entry to the base
> HTML container node/ root dom node. (Simply pass through to the underlying
> HTML tag)
> 3. In addition we want to support the various style states. So if they have a
> class called myClass we should automatically adjust that to myClassMouseOver
> the same way we do for built-in classes. Currently we have logic in
> AbstractWidgetBridge that will automatically change the class attribute to
> different permuations of the tag name, like "buttonMouseOver",
> "buttonMouseDown", etc. We should allow user-defined classes to use the same
> process and automatically add/remove state-specific permutations with mouse
> events.
