## How Do I Fix Iframe Size Issues on iOS Using CSS?

Resolving iframe Size Discrepancy on iOS Using CSS

In the realm of web development, it's essential to ensure website elements, such as iframes, behave consistently across different browsers and devices. However, instances arise where specific platforms may exhibit unexpected rendering behaviors.

A prime example is the issue of iframe sizing on iOS. When an iframe contains more content than fits within its designated frame, it typically overflows accordingly on browsers other than iOS. However, on iOS, Safari tends to resize the frame to accommodate the content, deviating from the intended design.

This behavior can be remedied by introducing a wrapper div and applying specific CSS properties to it. Specifically:

<code class="css">.wrapper {
  overflow: auto;
  -webkit-overflow-scrolling: touch;
}</code>

Integrating this wrapper div around the iframe allows for proper content overflow handling, even on iOS devices.

This solution draws its origins from previous observations and reports on Stack Overflow. Notably, the bug has been acknowledged since iOS 4, with additional insights available in resources such as:
