This evening I discovered a little bug that affects all sites hosted that use my Girder Framework and whilst it's not an astronomical issue and doesn't affect usability, it's one that makes some websites I've built using my framework less attractive.
Tonight I speak of parallax.
Many of you will know that a few of my websites use a parallax effect in several places. One of the most obvious is with the Jambour Digital website. Today I discovered that iPads and iPhones do not support parallax background images properly. In fact, they don't really support the background-attachment: fixed property at all.
In some ways, this makes sense due to the fact that scroll events on iOS devices are only triggered at the end of the scroll, for instance. Another reason is possibly because of battery life.
But what really gets to me as a designer is Apple's lack of understanding for developers who develop this stuff. Since a fallback would be difficult and would require at least JavaScript, Apple should have some kind of a backup for websites that rely on this.
So please Apple, fix this!
