I want to fill my page with a background image and have the text aligned in place with that background. With the below code, the background image loads at the top of the page, and the text goes under it. I know I can use the "background: " function, but the way it is done in my below code allows for automatic resizing, regardless of browser size (i.e., mobile devices have small browser sizes). So, I just want the background image to go behind the text.
<html>
<head>
<title>Title</title>
<style>
img.bg
{
min-height: 100%;
min-width; 781;
width: 100%;
height: auto;
top: 0;
left: 0;
z-index: -1;
}
#media screen and (max-width: 781)
{
img.bg
{
left: 50%;
margin-left: -390.5;
}
}
#container
{
position: relative;
width: 781;
margin: 50 px auto;
height: 758;
border: 1px solid black
}
#left
{
position: relative;
left: 1.280409731113956%;
top: 14.51187335092348%;
padding-top: 10px;
padding-left: 10px;
padding-right: 10px;
width: 50%;
height: 50%;
color: #FFFFFF;
position: relative;
}
p
{
font: 14px Georgia;
}
</style>
</head>
HTML
<img class="bg" src="background.jpg">
<div id="container">
<div id="left">
<p>
Text
</p>
</div>
</div>
</body>
</html>
Make your BG image have a z-index of 1, and your #container div to have a z-index of 2. Does that work?
img {
position: relative;
z-index: 1;
}
#container {
position: relative;
z-index: 2;
top: 0px;
left: 0px; /*or whatever top/left values you need*/
}
Just use position: fixed for your background image http://dabblet.com/gist/3136606
img.bg {
min-height: 100%;
min-width: 781px;
width: 100%;
top: 0;
left: 0;
position: fixed;
z-index: -1;
}
EDIT (I wish there was a way to make it more visible than this)
OK, after reading the comments for the original question, I understand that the purpose is to have a background that scales nicely for any display sizes.
Unfortunately, quite a lot of mobile devices have a problem with position: fixed - you can read more about this here.
So the best solution in this case is to use a background image, not an img tag, having the background-size set to 100% (which will stretch the image - example), or to cover (which will scale the image such that it completely covers the screen - example)
Well, maybe you can also try that css:
body{
background: url(images/bg.jpg) no-repeat center center fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
it's should cover all youre page even when page size is changed

Hi guys i am trying to create this effect with bootstrap 3 :
The black color being a random image and then just a white strip on were I can put my text etc.
So far I have this :
HTML:
<div class="parallax">
<div class="container">
<h1> Testing </h1>
</div>
</div>
CSS
.parallax {
background-image: url("../img/c.jpg");
min-height: 1000px;
background-attachment: fixed;
background-position: center;
background-repeat: no-repeat;
background-size: cover;
}
.container {
width: 800px;
}
However no matter what I change the width to for the container , it does not become smaller just the text inside of it does.
So again I am just looking to have a background image cover the whole browser and then just a white strip coming down but the width to be around 800px; so it leaves gaps on the side to see the image in the background
You can make use of min-width and max-width on container class. This ensures that when your browser is resized the sides are still visible by setting the width of the container to a relative (%) value. And the max-width limits it from extending beyond that. You can position the container using transform property in CSS and make an animation for the container to come from top and set its position to the vertical center of the webpage.
As far as the background is concerned, you can set the width or height to 100vw, 100vh or even % as you find suitable. This is just a demonstration.
.parallax {
background-image: url("http://via.placeholder.com/300x100");
height: 100vh;
background-attachment: fixed;
background-position: center;
background-repeat: no-repeat;
background-size: cover;
}
.container {
position: absolute;
left: 50%;
transform: translateX(-50%);
top: -300px;
background: white;
color: black;
min-width: 70%;
max-width: 800px;
height: 100px;
text-align: center;
animation: expand 2s linear forwards;
}
#keyframes expand {
0% {}
100% {
top: 50%;
transform: translate(-50%, -50%);
}
}
<div class="parallax">
<div class="container">
<h1> Testing </h1>
</div>
</div>
html
<div class="parallax">
<div class="cont">
hellowold
</div>
</div>
css
.parallax {
width: 100%;
height: 500px;
position: relative; // this is necessary
background: #000;
}
.cont {
position: absolute;
width: 100%; // for responsive it will take 100% width
max-width: 800px; // for bigger screen it will be max 800px
padding: 15px; // just for decoration
background: #fff;
box-sizing: border-box;
margin: 0 auto; // absoluted element center purpose
bottom: 0; // positioning at the bottom as per your image
left: 0; // absoluted element center purpose
right: 0;// absoluted element center purpose
text-align: center; // just for decoration
}
I am doing an animation with HTML and CSS3 and I need adapt along with the background image. The problem is that the content stay within that div. I put the height and width fixed for this but don’t work. When I try using dynamic proportions (% or auto) and background-size: contain; the animation does not follow the original path.
With fixed size following the path:
and mobile works fine too
but, not is responsive:
With dynamic size is responsive, but not follow path:
Changed code:
#main{
position:relative;
- left: 0;
- height: 1366px;
- width: 980px;
+ // left: 0;
+ height: 100%;
+ width: 100%;
overflow:hidden;
background: url('../images/bg.png');
background-repeat: no-repeat;
-
+ background-size: contain;
}
DEMO
This is my index.html
<div id="main">
<div class="participant" style="z-index: 4;">
<div class="car">
<img class="photo" src="https://scontent-atl3-1.xx.fbcdn.net/v/t1.0-1/c21.21.259.259/s50x50/529297_568082979888645_1727470385_n.jpg?oh=c75505b8b23ff9abd26be1fd5771f81d&oe=582BAD0F" alt="">
<img class="sprite" src="http://i.imgur.com/OwYhg9T.png" alt="">
</div>
</div>
</div>
And my animation.css
#charset "utf-8";
/* CSS Document */
body, html {
height: 100%;
}
body {
padding:0;
margin:0;
}
#main{
position:relative;
left: 0;
height: 1366px;
width: 980px;
overflow:hidden;
background: url("http://i.imgur.com/G4gs6EG.png");
background-repeat: no-repeat;
}
#-moz-keyframes move
{
from {
right: -30%;
top: 8%;
}
to {
right: 140%;
top: 80%;
}
}
#-webkit-keyframes move
{
from {
right: -30%;
top: 8%;
}
to {
right: 140%;
top: 80%;
}
}
.participant {
position: absolute;
display: inline-block;
height:200px;
width: 200px;
right: 140%;
top: 80%;
-moz-animation:move 10s linear infinite;
-webkit-animation:move 10s linear infinite;
}
.sprite{
width: 100%;
height: 100%;
}
.photo{
position: relative;
top: 128px;
left: 99px;
width: 50px;
height: 50px;
}
This is a little tricky and requires fixed aspect ratio of the background image.
1. Make everything responsive.
First of all, it won't work if everything is %-based but the car is px-based (because if you resize your window everything will get smaller but the car will stay the same), so for starters you are going to have to change the size of your car to percentages.
2. Fix aspect ratio.
Then you need to fix the aspect ratio using mix of absolute and relative positions and paddings.
In your case your wrapper's CSS will look something like:
width: 100%;
padding-bottom: 71.74%; /* 980/1366 = ~ 0.7174 */
(your background image is 980x1366px)
DEMO
3. FUTURE PROOF: Fill the screen on every screen.
Unfortunately you can't do much about white space around your image because of the aspect ratio itself, I'd personally look for a 16:9 image for the background and it will fit most of the desktop/laptop screens perfectly, if you need to cover wide range of screens then you should use media queries with different-sized backgrounds.
Remember to adjust the padding-bottom of your container along with the image itself.
Hope it helps!
Try replacing height and width in your #main css class to:
#main{
height: 100%;
width: 100%;
background: url("http://i.imgur.com/G4gs6EG.png") no-repeat fixed center;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
}
I've got this working on codepen.io
http://codepen.io/NosNits/pen/RRqzPy
I am currently using some code to display an image in a 'scale to fill' type of way. The code I am using was used on a project I did a while ago to crate a background image for a site and now I want to change the positioning from fixed to allow scrolling. However I can't work out the margins and sizing.
Here is the code:
<div id="Main Page">
<div id="Background">
<img src="http://googledrive.com/host/0By-qb7dZ_m5feE94MkcwSWxLckU" />
<style>
#Background{
position: fixed;
top: -50%;
left: -50%;
width: 200%;
height: 200%;
}
#Background img{
position: absolute;
top: 0;
left: 0;
right: 0;
bottom: 0;
margin: auto;
min-width: 50%;
min-height: 50%;
}
</style>
</div>
If you want to use the background-image for the entire site, you can use this css-code:
body {
background-image: url("http://googledrive.com/host/0By-qb7dZ_m5feE94MkcwSWxLckU");
background-attachment: fixed;
background-size: 100% 100%;
}
Depending on your background-image you can try background-size: cover; instead of background-size: 100% 100%; for a better result too.
Here is a fiddle-example: https://jsfiddle.net/hxefwhpL/
I', hoping this makes sense but I have HTML code that I have a child which is an svg animation, I'm wanting to have the section responsive so that the position of the svg stays where its meant to be on the map.
I have selected the coast of Africa as a point that I want to keep the SVG in place when the page is resized, but when it is resized you will see that the red marker moves across the rest of Africa.
You can see the jsFiddle for the Source Code and see the result to the full map.
.about-header__map .angola {
position: inherit;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
.about-header__map .angola svg {
top: 49%;
left: 42.5%;
position: absolute;
}
Use the width of the image (1440px) instead of width:100%
.about-header__map {
background: url(http://i.imgur.com/ZqQvEUK.png) no-repeat center center !important;
width: 1440px; /*here */
background-size: cover;
height: 500px;
position: absolute;
z-index: -1;
}
FIDDLE
Use a fixed width in .about-header__map
.about-header__map {
background: url(http://i.imgur.com/ZqQvEUK.png) no-repeat center center !important;
background-size: cover;
height: 500px;
position: absolute;
width: 1500px;
z-index: -1;
}
I'm trying to have a full screen image, easy enough with css using the code below.
width:100%;
height:100%;
background: url('photo2.jpg');
background-repeat: no-repeat;
background-position: center center;
background-attachment: fixed;
-webkit-background-size: cover;
-moz-background-size: cover;
-o-background-size: cover;
background-size: cover;
but the image is already placed in an html div, see here
<div class="fixed-background">
<img src="photo2.jpg"/>
</div>
It need's to be exactly how it would be using the css version, the only difference would be the image is called in html and not in the stylesheet.
try this
<style>
body {
height: 100%;
width: 100%;
margin: 0;
padding: 0;
}
.fixed-background {
position: absolute;
top: 0;
left: 0;
height: 100%;
width: 100%;
overflow: hidden;
}
.myimg {
height: inherit;
}
</style>
<html>
<body>
<div class="fixed-background">
<img src="public/dbs/images/1.jpg" class="myimg" />
</div>
</body>
</html>
Use object-fit: cover; on the <img> tag:
<div>
<img src="photo2.jpg" style="object-fit: cover;"/>
</div>
that parameter is a rather new thing (not all browsers supported), but that's the way to go. See also http://caniuse.com/#search=object-fit
Without using a background, consider this:
#mydiv {
position: absolute;
top: 50%;
right: 50%;
bottom: 50%;
left: 50%;
margin-top: -100px; /* (calculate half the height of your image) */
margin-left: -100px; /* (calculate half the width of your image) */
}
Full screen Image? you could do something like this through HTML
<div class="fixed-background">
<img src="photo2.jpg" height="100%" width="100%">
</div>
http://jsfiddle.net/pj73m4po/
EDIT:
or are you looking for something like this?
http://jsfiddle.net/pj73m4po/1/
Try the following: http://jsfiddle.net/pj73m4po/4/
Put your image in a div 100% high and wide. If you don't want your image to be stretched you don't want to use width and height seperately.
body {
height: 100%;
width: 100%;
margin: 0;
padding: 0;
}
.fixed-background {
position: absolute;
top: 0;
left: 0;
height: 100%;
width: 100%;
overflow: hidden;
}
img {
height: auto;
width: auto;
min-width: 100%;
min-height: 100%;
}
Instead use min-width and min-height. if you have a predefined image you can adjust the position in css. If you don't unfortunately you need javascript to center it.
The points that I gather from your css are the following:
Center the image
Fix the position of the image (so it doesn't scroll with the page)
Cover the viewport, scale proportionally to fit
That said, I suggest the following given your html
.fixed-background{
position:fixed;
width:100vh;
height:100vh;
overflow:hidden;
}
.fixed-background > img{
position:absolute;
width:100%;
height:auto;
top: 50%;
transform: translateY(-50%);
}
Honestly, I haven't tested the above but I would suspect you might get some weird results using fixed and absolute positioning together. But since the code defines the width and height directly using viewport units, it should be good. You might need 100vh of margin applied to a sibling element to get things to line up because position:fixed; will break the element out of the document flow.
