For some unknown reasons, iPad Safari doesn’t display a really long background image. In my example, the background image is 1,000 x 10,000 pixels. The same example works on any desktop browser e.g. Safari, Firefox, etc.

I am aware of the background-repeat in CSS but unfortunately it isn’t applicable in my specific case.

    Mobile Safari has limits to what size background images it will display before subsampling, you may be getting hit by this problem because of the size of your background:

    The maximum size for decoded GIF, PNG, and TIFF images is 3 megapixels for devices with less than 256 MB RAM and 5 megapixels for devices with greater or equal than 256 MB RAM.

    That is, ensure that width * height ≤ 3 * 1024 * 1024 for devices with less than 256 MB RAM. Note that the decoded size is far larger than the encoded size of an image.
