Great article, but am I missing something?:

<blockquote>Visitors with small-screen devices will see that link to the search results; visitors with larger screens will get the search results directly.</blockquote>

When I view the “See the result” page, it’s the same on my iPhone as it is on my desktop. The sidebar is always visible. I don’t see any link to the search results.

That page should be a working demo, right?
