For now this is only possible in Webkit and Mozilla browsers, the discussion about best implementation is still an ongoing project. You’ll have to use 2 rules, as the standards for this is not been set yet.

The <header> and <hgroup> tags are new for HTML5, we all know that <h1> – <h6> has vital importance in SEO to get keywords ranked on search engines such as Google. But it’s not as easy to understand the use for the new tags.
There are a lot of confusion around this HTML5 aside element. Its definition suggests it should be used for content surrounding the main content. The most common misconception of how this element should be used is for the standard sidebar. While there is usually a degree of relation between sidebar content and the content in an article, it is not enough to be considered fit for an aside. Navigation, ads, search boxes, blogrolls and so on are not directly related to the article and therefore do not justify the use of an aside.
