Fixed background image with ios7

Question

I have a project that I am using the fixed background image. It works great on everything except ios7. On the ipad the background image is zoomed in and blurry. Here is the CSS code I am using -

.header {
  display: table;
  height: 100%;
  width: 100%;
  position: relative;
  color: #fff;
  background: url(../images/boston2.jpg) no-repeat center center fixed; 
  -webkit-background-size: cover;
  -moz-background-size: cover;
  -o-background-size: cover;
  background-size: cover;
  }

here is a link to the live page - www.wdeanmedical.com

What am I missing?

Solution 1

Using background-attachment: fixed with background-size: cover causes issues on most mobile browsers (as you've seen). You can try using background-attachment: scroll. This won't give your desired effect, but you'll see the images at least. You could use a media-query or two to limit it to devices that are tablets or phones by using @media screen and (max-device-width: 1024px){}

OR

You can use background-position: scroll and include some javascript that will keep the image at the scrolled position (keeping it at the top of the window): DEMO

Solution 2

Know this is an old thread, but wanted to provide an updated solution that builds on the solution from @Cruz-Nunez

Relying on viewport size is liable to fail. For example, relying on a 767px viewport won't work on iPads, and increasing the size negates the benefit of this approach.

Instead, you can check if the device has hover capabilities, and if it doesn't, override like this:

@media (hover: none) {
   .homeHero {
       background-attachment: initial;
   }
}

You can also check if the device has a coarse pointer (e.g. a finger) instead of a fine one (e.g. a mouse):

@media (pointer: coarse) { ... }

I had a very simple solution for this, after struggling with all the methods of fixing this.

i had the problem on my mobile IOS devices.

css (desktop)

#ci-hero-11 .widget-wrap , #ci-hero-12 .widget-wrap {
background-size: auto;
background-attachment: fixed;
}

.widget-wrap {
background-attachment: scroll;
}

Then i overwrite it with media query removing "fixed" as background attachment.

css (mobile)

/*-------- iPads (portrait and landscape) --------*/
@media only screen 
and (min-device-width : 768px) 
and (max-device-width : 1024px) {
#ci-hero-11 .widget-wrap , #ci-hero-12 .widget-wrap {

    background-attachment: initial;

}
}

initial - Sets this property to its default value. I think because IOS doesn't accept 'fixed' it falls back to a default value it accepts, scroll.

This worked for me on every device. Hope it helps someone else as well.

Solution 4

EDIT: Sep 2020 This broke for some iPads so I now use:

@supports (-webkit-touch-callout: inherit) {
  .paral {
  background-attachment: scroll;
  }
}

Original Post: Combining the ideas of @brouxhaha and @yllama: Use a media query that targets iOS, which is found at this SO post, to set

    background-attachment: scroll;

This way the fixed background image appears for non-iOS mobile and all other devices.

.widget-wrap {
   background-attachment: fixed;
   ...
   ...
}

@supports (-webkit-overflow-scrolling: touch) {
  .widget-wrap {
  background-attachment: scroll;
  }
}

Solution 5

Try this:

HTML

<div class="container">
  <div class="fixed-img"></div>
  <h1>Words that go over text</h1>
</div>

css

.fixed-img {
  position: fixed;
  z-index: -1;
}

But if you have parallax happening, not using 'fixed' will break the parallax. A question marked as a 'duplicate' of this one has much more info and references to workarounds. See here: stackoverflow.com/questions/23236158/…

Say I had several horizontal sections on my page and I wanted to use this effect in the bottom div, how can I make this work? This code only works if the image is on the top of the page.

[brouxhaha]

You probably need to either ask a new question or provide more detail because I have no idea what you're trying to do.

[mems]

You can use a pseudo element instead: .container::before{content: "";display: block;position: fixed;z-index: -1;height: 100%;width: 100%}, and you don't need to add any element in DOM

[Frank Conijn - Support Ukraine]

Could you make a live demo? (Not on CodePen or JSFiddle because they work with iframes, in which iOS will not fixate anything.)

[Frank Conijn - Support Ukraine]

@BjørnBørresen -- The JSFiddle indeed does not work, but that is because it works with iframes and iOS will not fixate anything in iframes, regardless of the code. The Live example Cruz is linking to does work on my iPad Pro 11.3. Or for a more bare-bones example, check out newskiinstruction.com/bgtest.html.

This is a great answer. I just learned of hover: none. Thanks!

[Fabian von Ellerts]

This is probably the best way for now, too bad @supports not (background-attachment: fixed) doesn't work.

[jalmatari]

background-size: 100% 100%;

[Beanie]

doesnt work on safari mobile, well unless you want the image resizing and bouncing around the screen

[shihao316558512]

the base way for now

[mike]

Summary of this solution: Instead of using background-attachment: fixed;, add a background image to a position: fixed; div.

This answer should be accepted - would have saved me time.

[frenchie]

This should be the accepted answer: it works like a charm. Great job!!
