Stretch and Scale CSS Background

Stretch and scale CSS background

For modern browsers, you can accomplish this by using background-size:

body {
    background-image: url(bg.jpg);
    background-size: cover;
}

cover means stretching the image either vertically or horizontally so it never tiles/repeats.

That would work for Safari 3 (or later), Chrome, Opera 10+, Firefox 3.6+, and Internet Explorer 9 (or later).

For it to work with lower verions of Internet Explorer, try these CSS:

filter: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='.myBackground.jpg', sizingMethod='scale');
-ms-filter: "progid:DXImageTransform.Microsoft.AlphaImageLoader(src='myBackground.jpg', sizingMethod='scale')";

Stretch and scale a CSS image in the background - with CSS only

CSS3 has a nice little attribute called background-size:cover.

This scales the image so that the background area is completely covered by the background image while maintaining the aspect ratio. The entire area will be covered. However, part of the image may not be visible if the width/height of the resized image is too large.

How to stretch the background image to fill a div

Add

background-size:100% 100%;

to your css underneath background-image.

You can also specify exact dimensions, i.e.:

background-size: 30px 40px;

How do I stretch a background image to cover the entire HTML element?

<style>
    { margin: 0; padding: 0; }

    html { 
        background: url('images/yourimage.jpg') no-repeat center center fixed; 
        -webkit-background-size: cover;
        -moz-background-size: cover;
        -o-background-size: cover;
        background-size: cover;
    }
</style>

CSS stretch or fit background image

EDIT:

You tried background-size: 100%,

CSS interprets this as 100% width, automatic height which will look like this:

background-size: 100% auto;

What you want is the second argument (height) to be 100% too, so you should do this:

background-size: 100% 100%;

END EDIT

Try:

background-size: cover;

This will fit the width or height and overflow the rest

Or:

background-size: contain;

This will make the image as large as possible without changing it's aspect ratio.

CSS Image size, how to fill, but not stretch?

You can use the css property object-fit. ("sets how the content of a replaced element, such as an <img> or <video>, should be resized to fit its container.")

.cover {
  object-fit: cover;
  width: 50px;
  height: 100px;
}

<img src="http://i.stack.imgur.com/2OrtT.jpg" class="cover" width="242" height="363" />
