"My layout shifts when scrolling down on an iPhone because the browser address bar hides. How do I stop this?"
Expert Solution
When it comes to web performance, nothing frustrates potential clients more than a slow mobile page load. Let's examine the mechanics of Fixing CLS Caused by Mobile Viewport Resizing and map out a lightweight solution to speed up your website.
The Core Issue: Expert Solution
Mobile browsers change the viewport height dynamically when the address bar collapses on scroll. If you use `100vh` for full-screen sections, it forces a layout shift. Replace `100vh` with the new dynamic viewport units `100dvh` (Dynamic Viewport Height). This natively accounts for browser UI changes without triggering recalculations or Cumulative Layout Shifts.
