Fixed Photos in colour section aren't responsive on mobile device

Hi,

Enfold Theme: I have a photo in one of my colour sections and its set to ‘fixed’. On the desktop screen it moves with the page when i scroll up and down and you can see the entire photo when it moves, like a parallax.

But when i look at it on my mobile phone (iPhone 6) the photo doesn’t move at all, it’s just still (it’s not moving in the background like on the desktop). When i scroll down the page the top of the photo is cut off and doesn’t look how i want it to look. I have tried changing it to ‘parallax’ and ‘scroll’ but the issue still remains.

I want it to be exactly like it appears on a desktop, with the image moving in a parallax way.

Or maybe it’s just not responsive on mobile devices?

Thanks,
Sam :)
