I have this HTML:
<div className="img" />
with this Css:
.row2 {
position: relative;
width: 1790px;
height: 983px;
background-image: url("/img.png");
background-repeat: no-repeat;
background-position: center;
background-size: cover;
background-color: #d0c6b5;
background-blend-mode: multiply;
#media (min-width: 375px) and (max-width: 414px) {
}
}
and i`m going to use media query to show only this part of the screen.
how can i do?
For responsive designing's you will not be able to get the exact crop for all the dimensions. However you can use px to get almost the same crop for the devices.
Mainly you have to play around the background-position attribute. See reference code below
#media (min-width: 375px) and (max-width: 414px) {
width: 350px;
height: 600px;
background-image: url('https://i.stack.imgur.com/aIWX6.png');
background-position: -950px 0;
background-size: 650px 100%;
}
There is a lot of code in this one, so I'm going to put it in a codepen.

Basically I am using #media queries to extend the #about div to be taller as my content is literally going into another div on mobile devices. I need the blue background to extend below the placeholder image so it's all in the same section.
Media Query:
/*MOBILE SUPPORT*/
#media screen and (max-width: 768px) {
#about {
height: 120vh !important;
background: rgb(12, 18, 71);
background-size: cover;
}
}
Change the height to auto
/*MOBILE SUPPORT*/
#media screen and (max-width: 768px) {
#about {
height: auto !important;
background: rgb(12, 18, 71);
background-size: cover;
}
}
Is there any way to only trigger the Parralax effect on laptop and desktop views?
Atm I have the following however, it doesn't allow an image to be displayed on some device browsers: Safari to be specific.
.parralax {
/* Full height */
height: 100%;
/* Create the parallax scrolling effect */
background-attachment: fixed;
background-position: center;
background-repeat: no-repeat;
background-size: cover;
}
My HTML solely references this in the section I want the Parralax effect.
<section id="home" class="home parralax bg-img fix">
Make sure you put your external style sheet first in the document so it overwrites your parallax rules.
/*Mobile 480px*/
/*Desktop 992px*/
/*Huge 1280px*/
#media screen and (min-width: 480px) and (min-width: 768px), (min-width: 992px), (min-width: 1280px) {
.parralax {
/* Full height */
height: 100%;
/* Create the parallax scrolling effect */
background-attachment: fixed;
background-position: center;
background-repeat: no-repeat;
background-size: cover;
}
}
I put this together to display a background on the left and right side of a website.
Now with this in place the body container is appearing much wider than it was before. Why would this be?
Can anybody see what isn't good code in the below?
div#multi-background {
width: 100%;
height: 100%;
background-image: url(http://cdn.shopify.com/s/files/1/0834/6311/t/2/assets/right-1.png), url(http://cdn.shopify.com/s/files/1/0834/6311/t/2/assets/left-1.png);
background-position: center right, top left;
background-repeat: no-repeat;
}
#media only screen and (min-width: 481px) {
//Happens when the screen size is >= 481px
div#multi-background {
width: 100%;
height: 100%;
background-image: url(http://cdn.shopify.com/s/files/1/0834/6311/t/2/assets/right-1.png), url(http://cdn.shopify.com/s/files/1/0834/6311/t/2/assets/left-1.png);
background-position: center right, top left;
background-repeat: no-repeat;
}
}
#media only screen and (max-width: 481px) {
//Happens when the screen size is <= 481px
div#multi-background {
background-image: none;
}
}
Fiddle - http://jsfiddle.net/timsalabim/1mk097vb/8/
If I got it right, this would be the code you want:
#multi-background {
height: 700px;
background-image: url(http://cdn.shopify.com/s/files/1/0834/6311/t/2/assets/right-1.png), url(http://cdn.shopify.com/s/files/1/0834/6311/t/2/assets/left-1.png);
background-position: center right, top left;
background-repeat: no-repeat;
}
#media screen and (min-device-width: 481px) {
/*Happens when the screen size is bigger than 481px */
#multi-background {
width: 100%;
background-image: url(http://cdn.shopify.com/s/files/1/0834/6311/t/2/assets/right-1.png), url(http://cdn.shopify.com/s/files/1/0834/6311/t/2/assets/left-1.png);
background-position: center right, top left;
background-repeat: no-repeat;
}
}
#media screen and (max-device-width: 481px) {
/*Happens when the screen size is lower than 481px*/
#multi-background {
background-image: none;
}
}
<body><div id="multi-background"></div>
The comments were not written with "/" and "/". There were problems with #media declaration and height issues for more than 481 px.
Hope it helps.
Hi I have several divs on my page which have background images that I want to expand to cover the entire div which in turn can expand to fill the width of the viewport.
Obviously background-size: cover behaves unexpectedly on iOS devices. I've seen some examples of how to fix it, but I can't make them work in my situation. Ideally I'd prefer not to add extra <img> tags to the HTML but if it's the only way then I will.
Here is my code:
.section {
margin: 0 auto;
position: relative;
padding: 0 0 320px 0;
width: 100%;
}
#section1 {
background: url(...) 50% 0 no-repeat fixed;
background-size: cover;
}
#section2 {
background: url(...) 50% 0 no-repeat fixed;
background-size: cover;
}
#section3 {
background: url(...) 50% 0 no-repeat fixed;
background-size: cover;
}
<body>
<div id="section1" class="section">
...
</div>
<div id="section2" class="section">
...
</div>
<div id="section3" class="section">
...
</div>
</body>
The question is, how can I get the background image to completely cover the section div, taking into account the variable width of the browser and the variable height of the content in the div?
I have had a similar issue recently and realised that it's not due to background-size:cover but background-attachment:fixed.
I solved the issue by using a media query for iPhone and setting background-attachment property to scroll.
For my case:
.cover {
background-size: cover;
background-attachment: fixed;
background-position: center center;
#media (max-width: #iphone-screen) {
background-attachment: scroll;
}
}
Edit: The code block is in LESS and assumes a pre-defined variable for #iphone-screen. Thanks for the notice #stephband.
I've had this issue on a lot of mobile views I've recently built.
My solution is still a pure CSS Fallback
http://css-tricks.com/perfect-full-page-background-image/ as three great methods, the latter two are fall backs for when CSS3's cover doesn't work.
HTML
<img src="images/bg.jpg" id="bg" alt="">
CSS
#bg {
position: fixed;
top: 0;
left: 0;
/* Preserve aspect ratio */
min-width: 100%;
min-height: 100%;
}
Also posted here: "background-size: cover" does not cover mobile screen
This works on Android 4.1.2 and iOS 6.1.3 (iPhone 4) and switches for desktop. Written for responsive sites.
Just in case, in your HTML head, something like this:
<meta name="viewport" content="width=device-width, initial-scale=1.0"/>
HTML:
<div class="html-mobile-background"></div>
CSS:
html {
/* Whatever you want */
}
.html-mobile-background {
position: fixed;
z-index: -1;
top: 0;
left: 0;
width: 100%;
height: 125%; /* To compensate for mobile browser address bar space */
background: url(/images/bg.jpg) no-repeat;
background-size: 100% 100%;
}
#media (min-width: 600px) {
html {
background: url(/images/bg.jpg) no-repeat center center fixed;
background-size: cover;
}
.html-mobile-background {
display: none;
}
}
There are answers over the net that try to solve this, however none of them functioned correctly for me. Goal: put a background image on the body and have background-size: cover; work mobile, without media queries, overflows, or hacky z-index: -1; position: absolute; overlays.
Here is what I did to solve this. It works on Chrome on Android even when keyboard drawer is active. If someone wants to test iPhone that would be cool:
body {
background: #FFFFFF url('../image/something.jpg') no-repeat fixed top center;
background-size: cover;
-webkit-background-size: cover; /* safari may need this */
}
Here is the magic. Treat html like a wrapper with a ratio enforced height relative to the actual viewport. You know the classic responsive tag <meta name="viewport" content="width=device-width, initial-scale=1">? This is why the vh is used. Also, on the surface it would seem like body should get these rules, and it may look ok...until a change of height like when the keyboard opens up.
html {
height: 100vh; /* set viewport constraint */
min-height: 100%; /* enforce height */
}
That its the correct code of background size :
<div class="html-mobile-background">
</div>
<style type="text/css">
html {
/* Whatever you want */
}
.html-mobile-background {
position: fixed;
z-index: -1;
top: 0;
left: 0;
width: 100%;
height: 100%; /* To compensate for mobile browser address bar space */
background: url(YOUR BACKGROUND URL HERE) no-repeat;
center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
background-size: 100% 100%
}
</style>
For Safari versions <5.1 the css3 property background-size doesn't work. In such cases you need webkit.
So you need to use -webkit-background-size attribute to specify the background-size.
Hence use -webkit-background-size:cover.
Reference-Safari versions using webkit
I found the following on Stephen Gilbert's website - http://stephen.io/mediaqueries/. It includes additional devices and their orientations. Works for me!
Note: If you copy the code from his site, you'll want to edit it for extra spaces, depending on the editor you're using.
/*iPad in portrait & landscape*/
#media only screen and (min-device-width : 768px) and (max-device-width : 1024px) { /* STYLES GO HERE */}
/*iPad in landscape*/
#media only screen and (min-device-width : 768px) and (max-device-width : 1024px) and (orientation : landscape) { /* STYLES GO HERE */}
/*iPad in portrait*/
#media only screen and (min-device-width : 768px) and (max-device-width : 1024px) and (orientation : portrait) { /* STYLES GO HERE */ }
#media (max-width: #iphone-screen) {
background-attachment:inherit;
background-size:cover;
-webkit-background-size:cover;
}
I found a working solution, the following CSS code example is targeting the iPad:
#media only screen and (min-device-width : 768px) and (max-device-width : 1024px) {
html {
height: 100%;
overflow: hidden;
background: url('http://url.com/image.jpg') no-repeat top center fixed;
background-size: cover;
}
body {
height:100%;
overflow: scroll;
-webkit-overflow-scrolling: touch;
}
}
