Dialog management

[jgauffin]

I love the overall approach to the semantic HTML and CSS.

However, when working with WebComponents there are some troubles.

For instance, when using dialogs, it's often the parent component that decides if the child component should be in a dialog.

So it's parent -> dialog -> child -> header/div/footer.

In that scenario, the CSS won't work as the header/footer does not direct children to the dialog. Isn't it enough to style any header/footer in a dialog? Having more than one seems to a pretty bad dialog design :)
