If you're into web design, you might've noticed that some websites have this neat trick where the iPhone navigation bar stays maximized as you scroll.

Now, you're probably wondering, "How do they achive this?" Especially when that auto-minimizing nav bar can mess with your bottom-fixed UI elements.

Here's the hack: You wrap your entire website content in a new div element. That way, even though your users think they're scrolling down the page, they're actually just navigating within that div. The result? A static iPhone navigation bar that doesn't expand or shrink, making for a consistent and slick user experience.

So, first step: Encapsulate all your website content inside a new div element.

<div id="wrapper">
  <!-- Your entire site content -->
</div>

Now, let's add some CSS to make this work.

body, html {
  height: 100%;
  margin: 0;
  overflow: hidden;
}

#wrapper {
  position: fixed;
  top: 0;
  left: 0;
  right: 0;
  bottom: 0;
  overflow-y: scroll;
  -webkit-overflow-scrolling: touch;
}

You're basically putting the viewport on lockdown. With position: fixed, you're anchoring that new div to the top of the browser window, while allowing the content inside to move freely. This clever maneuver keeps the iPhone's navigation bar from bouncing around like it usually does, giving your users a more stable experience.
