Modernizr on the Server-Side

Modernizr on the Server-Side:

James Pearce:

The current vogue seems to be to do as much [adjusting web content] as possible on the client-side: media queries, progressive enhancement, adding CSS body classes, and so on….

In my opinion, this approach won't always cut it. I've already pointed out that the users of radically different devices might want downright different things. Sometimes the differences between browsers are just too great to be able to deal with once the page has reached the client. And dealing with structural changes to a site's information architecture based on browser capabilities gets messy, fast.

The "already pointed out" part James refers to is an article he wrote previously: Not a mobile web, merely a 320px-wide one. Also worth reading.
