I want to set a background image to different divs, but my problems are:
How can I stretch the background-image to fill the whole background of the div?
#div2{
background-image:url(http://s7.static.hootsuite.com/3-0-48/images/themes/classic/streams/message-gradient.png);
height:180px;
width:200px;
border: 1px solid red;
}

background-image
.selector{
background-size: cover;
/* stretches background WITHOUT deformation so it would fill the background space,
it may crop the image if the image's dimensions are in different ratio,
than the element dimensions. */
}
Max. stretch without crop nor deformation (may not fill the background): background-size: contain;
Force absolute stretch (may cause deformation, but no crop): background-size: 100% 100%;
Absolute positioning image as a first child of the (relative positioned) parent and stretching it to the parent size.
HTML
<div class="selector">
<img src="path.extension" alt="alt text">
<!-- some other content -->
</div>
background-size: cover;
:To achieve this dynamically, you would have to use the opposite of contain method alternative (see below) and if you need to center the cropped image, you would need a JavaScript to do that dynamically - e.g. using jQuery:
$('.selector img').each(function(){
$(this).css({
"left": "50%",
"margin-left": "-"+( $(this).width()/2 )+"px",
"top": "50%",
"margin-top": "-"+( $(this).height()/2 )+"px"
});
});
Practical example:
background-size: contain;
:This one can be a bit tricky - the dimension of your background that would overflow the parent will have CSS set to 100% the other one to auto. Practical example:
.selector img{
position: absolute; top:0; left: 0;
width: 100%;
height: auto;
/* -- OR -- */
/* width: auto;
height: 100%; */
}
background-size: 100% 100%;
:.selector img{
position: absolute; top:0; left: 0;
width: 100%;
height: 100%;
}
PS: To do the equivalents of cover/contain in the "old" way completely dynamically (so you will not have to care about overflows/ratios) you would have to use javascript to detect the ratios for you and set the dimensions as described...
by using property css:
background-size: cover;
To keep the aspect ratio, use background-size: 100% auto;
div {
background-image: url('image.jpg');
background-size: 100% auto;
width: 150px;
height: 300px;
}
Use: background-size: 100% 100%; To make background image to fit the div size.
body{
margin:0;
background:url('image.png') no-repeat 50% 50% fixed;
background-size: cover;
}
For this you can use CSS3 background-size
property. Write like this:
#div2{
background-image:url(http://s7.static.hootsuite.com/3-0-48/images/themes/classic/streams/message-gradient.png);
-moz-background-size:100% 100%;
-webkit-background-size:100% 100%;
background-size:100% 100%;
height:180px;
width:200px;
border: 1px solid red;
}
Check this: http://jsfiddle.net/qdzaw/1/
You can add:
#div2{
background-image:url(http://s7.static.hootsuite.com/3-0-48/images/themes/classic/streams/message-gradient.png);
background-size: 100% 100%;
height:180px;
width:200px;
border: 1px solid red;
}
You can read more about it here: css3 background-size
Try something like this:
div {
background-image: url(../img/picture1.jpg);
height: 30em;
background-repeat: no-repeat;
width: 100%;
background-position: center;
}
You can use:
background-size: cover;
Or just use a big background image with:
background: url('../images/teaser.jpg') no-repeat center #eee;
