[Solved] Full Page Backgrounds on iOS (background-size: cover)

[TheDoc]

I must be going crazy here. I don’t understand how my searches for a solution to this come up empty. It only means that I’m doing something completely wrong or nobody cares about the issue.

I’m using `background-size: cover;` to create a full-page background image on the body. More info on that, if you’re interested, can be found here: https://css-tricks.com/perfect-full-page-background-image/

This works perfectly across all desktop browsers (I even have a fix in place for IE7 and IE8) but pesky little iOS does not want to play nice. Instead of using the *viewport* height it uses the `body` height which, especially on a site that has infinite scroll, can get very long. This results in a completely distorted and unrecognizable background image.

Open that up on your desktop to see how it should function, then open it up on an iPhone/iPad to see where it all falls apart.

Any advice would be greatly appreciated.

For now I’m using **CSS-Only Technique #2** for iOS.

Any love here?

@TheDoc I tried relentlessly when you posted this and found no solution. Have you tried posting on Stack Overflow?

[TheDoc]

I haven’t – a great idea.

@TheDoc check this page out and see if you can figure it out. It works on iOS.

It works, but not like it should.

What that page is doing is stretching the background image the entire length/width of the document, not of the screen size. So imagine if you had a blog with infinite scroll, the image would stretch and get blurrier as you added new posts to the page.

Bummer.

[TheDoc]

Well, right now I’m essentially doing that except with an image.

I updated my 2nd comment as I’m now using *CSS-Only Technique #2* for iOS. The problem is that mobile Safari really doesn’t handle fixed elements very well. The issue comes into play when users zoom in/out of the page the `#bg` tries to resize itself.

I think it might just have to be something that I accept, I just don’t understand how nobody has a 100% working solution for it.

@TheDoc I doubt she’ll know but ask @sazzy on Twitter. This would be a great article for @chriscoyier to blog about.

One more kicker: the image being used can have any dimension as it will be user-uploaded.

Did anybody find a clean solution for this? I was digging through piles of Google Search results…

this one works for me…it’s jquery, but oh well:

I was looking at a solutions for this as well…

I can get backgrounds to display correctly by combining background-size: cover with background-attachment: scroll.
