Replicating Background-Attachment: Fixed Behavior on iOS

Exploring the Issue

When using background-attachment: fixed to achieve fixed background images on iOS, developers encounter issues with unexpected sizing and lack of scrolling effects. This issue arises due to Safari on iOS disabling background attachments to enhance scrolling performance.

Understanding the Browser Limitation

According to @PaulIrish, fixed-backgrounds impose a significant repaint cost, negatively impacting scrolling performance. Consequently, Safari on iOS has disabled this behavior.

Alternative Approaches

Since background-attachment: fixed is not supported on iOS, alternative solutions can be explored:

• Fixed Position DIV:

  • Create a position: fixed; DIV and place the background image within it.
  • Clip the DIV using a position: relative; parent DIV.
  • This technique provides a workaround by simulating fixed background behavior without using background-attachment: fixed.
