The end result is shown in Figures 4 through 8. No, they aren't identical; with screen sizes that vary as much as these devices do, they shouldn't be. But they're all clear and readable, and that's what matters when you're on the move.

With some simple Web technologies, it's not difficult to make your site feel friendly to even the smallest among us. Hopefully, you've seen that you can get a start without a whole lot of effort.

After you've become comfortable with these techniques, you can take the next step and work with the user agent detection method I described for Android. From there, you can detect other devices and load specific style sheets for each to invoke more layout-oriented CSS functions.
