Yes, there have been reported issues with fixed background images on iOS devices in Webflow. This issue occurs because of how iOS handles background-attachment: fixed property.
The problem is that iOS devices treat fixed background images differently from desktop browsers. On iOS, instead of fixing the background image in place and making the content scroll over it, the fixed background image will scroll with the page.
This behavior is not specific to Webflow but is a general characteristic of iOS devices. It's important to note that this issue doesn't affect all versions of iOS or all versions of the Safari browser on iOS. It often occurs in older versions, but it's recommended to test on different iOS devices and versions to ensure compatibility.
To work around this issue, you can use custom code or a workaround within Webflow. Here's a possible solution:
1. Add a new section to your page and set its position to relative.
2. Inside this section, add a div block with a fixed position and the dimensions you want for your background image.
3. Set the background image for this div block.
4. Set the z-index of this div block to a higher value than other elements on your page to ensure it appears as the background.
5. Decrease the height of the section containing the content of your page to create space for the fixed background image.
By using this workaround, the background image will appear fixed on iOS devices, even though it's technically a scrollable div within the page.
It's worth mentioning that this solution might not work in all cases. iOS updates and browser changes can affect how this workaround behaves, so it's essential to test and ensure compatibility across different devices and versions of iOS.
Additionally, it's always a good practice to provide alternative styling or fallbacks for fixed background images on iOS devices to ensure a consistent and pleasing experience for all users.
