title: Disable double tap zoom on iOS. User-scalable doesn't fully work
body: <p>I'm using user-scalable=no in my viewport meta tag to disable double tap zooming in iOS. Almost everything seems to work as I wanted except a few very small and specific spots still allow me to zoom by double tapping in the iPhone simulator. Why is this so? Is there some css or other meta tags that could negate the viewport meta tag settings in such small specific areas? Any ideas?</p>
