Background image not showing on iPad and iPhone
There's a problem with your CSS rule:
Your using the shorthand notation in which the background-size
-property comes after the background-position
-property and it must be separated by a /
.
What you're trying to do is to set the position, but it will fail as auto
is not a valid value for it.
To get it to work in shorthand notation it has to look like this:
background: url([URL]) 0 0 / auto 749px;
Also note that there's a value called cover
, which may be suitable and more flexible here:
background: url([URL]) 0 0 / cover;
The support for background-size
in the shorthand notation is also not very broad, as it's supported in Firefox 18+, Chrome 21+, IE9+ and Opera. It is not supported in Safari at all. Regarding this, I would suggest to always use:
background: url("background1.png");
background-size: auto 749px; /* or cover */
Here are a few examples and a demo, to demonstrate that behavior. You'll see that Firefox for example shows every image except the fist one. Safari on the other hand shows only the last.
CSS
section {
width: 200px;
height: 100px;
border: 1px solid grey;
}
#section1 {
background: url(http://placehold.it/350x150) auto 100px;
}
#section2 {
background: url(http://placehold.it/350x150) 0 0 / auto 100px;
}
#section3 {
background: url(http://placehold.it/350x150) 0 0 / cover;
}
#section4 {
background: url(http://placehold.it/350x150) 0 0;
background-size: cover;
}

Background Image not Displaying Correctly in iOS
Have you tried hardware acceleration? Add -webkit-transform: translateZ(0);
to the same css as your adding the background. This is my guess because it appears to be a rendering issue and hardware acceleration fixes rendering issues when you use css transitions in Chrome.
#wrap {
margin:0 auto;
position:relative;
padding:0;
background: #B3B1B2 url(/images/bgs/parchment2.jpg);
-webkit-transform: translateZ(0);
}
Or maybe try retina display images for devices that support them using media queries?
@media (-webkit-min-device-pixel-ratio: 2), (min-resolution: 192dpi) {
#wrap {
background: #B3B1B2 url(/images/bgs/parchment2_2x.jpg);
}
}
Media Query source *
To solve the rendering issues you can try adding -webkit-transform: translateZ(0);
to other tags that are also wrapping content on the page. This may prevent loading/rendering issues.
Background Images not displayed correctly on Iphone and Ipad
Hi Christin you should insert a media queries and replace the background-attachment for "scroll". Please see below:
@media only screen and (min-width: 768px){
.bg-1 {
background: url('../Dateien/sharkGround1920.jpg') no-repeat center center fixed;
background-size: cover;
background-attachment:scroll !important;
}
}
Background image not displayed properly on iPad and iPhone
I've found the following solution to fix the ipad and iphone problem:
/* fix for the ipad */
@media (min-device-width : 768px) and (max-device-width : 1024px) {
#home {
background-attachment: scroll;
/* default height landscape*/
height: 768px;
}
.ipadfix{
height: 300px !important;
}
img.ipadfix{
width:100% !important;
height:auto !important;
}
}
/* fix for the ipad */
@media (min-device-width : 768px) and (max-device-width : 1024px) and (orientation: portrait) {
#home {
/* default height landscape*/
height: 1024px;
}
}
/* fix for the iphone */
@media (min-device-width : 320px) and (max-device-width : 568px) {
#home {
background-attachment: scroll;
/* default height landscape*/
height: 320px;
}
.ipadfix{
height: 150px !important;
}
img.ipadfix{
width:100% !important;
height:auto !important;
}
}
/* fix for the iphone */
@media (min-device-width : 320px) and (max-device-width : 568px) and (orientation: portrait) {
#home {
/* default height landscape*/
height: 568px;
}
}
background images don't show/are stretched on iPad or iPhone
You can either:
- use a fixed position, with a background position
center center
: see "CSS background-size: cover replacement for Mobile Safari".
This page refers to abackground-attachment: fixed;
as well, while remining use that viewport values (such asvh
andvw
) are technically supported on iOS 7 but simply do not work, hence therodneyrehm/viewport-units-buggyfill
project. - or (less elegant), use fixed size for media with a given size: see "Background image not displayed properly on iPad and iPhone"
