Hi Christina.

Yes this used to enjoy life as a component, which I kind of preferred as I like using it twice in a block to step the user through a model with changing backgrounds per step. The component version (v1.0.3) is still available here.

Having said that I can't seem to replicate your issue with the extension version on ios Safari. Are you sure you don't have any old background images blocking the view at block/component level?

Hi Barry,

thanks for the hint! At last I downloaded the component version as well, but unfortunately I can't get it to work (independent of the system). Looking in the developer tools of my chrome browser I found out that somehow the structure of the component is not implemented properly (see image #1 - #2 shows how it should normally look like). But unfortunately I have no idea what might be the reason for this...

 

I also did some further investigation of the extension version of the BackgroundScroll feature on different Apple devices - iPad Mini, Mac OS (using Safari 12.1.1) and of course again the iPhone (iPhone 6S using Safari 12.1). And I found out that obviously the images are there, but they are - why ever - on the iPhone as well as on the iPad Mini (not on the Mac OS) scaled up in an exorbitant way (see image iPhone). And even if I see a picture, if I scroll down it ends and then there is nothing (see 2nd image of the iPhone).(The Android image shows the correct appearance: I have 2 images of the same situation - one at daylight, the other one at nighttime; by scrolling you can swap between them)

So, any idea what might be going wrong on the iPhone?

I really like the user to be able to change from day to night by his own action and would only reluctantly abandon it...

 

Kind regards,

Christina

Ah the component issue was probably to do with your newer versions of AT/framework. I was using the component version in AT 0.6.5 / 2.3.3 on which I still have a number of courses to maintain.

What's defined for your background-size and background-attachment for the image issue in iOS? Something in iOS safari might be overriding. Happy to inspect and check it out if you can send me a sample zip of the issue. :)

Hi Barry,

 

thanks a lot for your help!

Here are the zip files - one is the published course and the other one is the export version.

Maybe you'll find something I have been overlooking all the time...

 

Kind regards,

Christina

 

PS: The course actually uses its own theme. But unfortunately I could not use this original theme for the sample files, because the file size got over 10 MB. So I had to use the Vanilla theme. But this makes no difference to the problem with the BackgroundScroll extension...
