How Can I Simulate `background-attachment: fixed` on iOS?

Preserving Background-Attachment Fixed Functionality on iOS

Emulating the behavior of the background-attachment property set to fixed on iOS devices can be challenging due to its inherent limitations.

The property typically assigns elements a background image that remains stationary while the webpage scrolls. However, this functionality is disabled on iOS platforms due to its high computational cost, as explained by Chrome developer Paul Irish.

As an alternative, several workarounds have emerged:

• Using a position:fixed Div: Create an absolutely positioned
  with the desired background image and clip its overflow by placing it within a position:relative parent

  . This approach can provide a similar effect to background-attachment: fixed, but with potential limitations.
• Viewport Background: Utilize the HTML5 specification's viewport tag to set a background image. This technique achieves a fullscreen background that doesn't scroll with the page, simulating the fixed background effect.

It's important to note that these methods may not perfectly replicate the functionality of background-attachment: fixed on iOS devices. They offer alternative solutions to achieve a similar visual effect while minimizing the performance impact.
