Thanks to CSS3 there is a solution !
The solution is to put the image as background-image
and then set the background-size
to contain
.
HTML
<div class="bounding-box">
</div>
CSS
.bounding-box {
background-image: url(...);
background-repeat: no-repeat;
background-size: contain;
}
Test it here: http://www.w3schools.com/cssref/playit.asp?filename=playcss_background-size&preval=contain
Full compatibility with latest browsers: http://caniuse.com/background-img-opts
To align the div in the center, you can use this variation:
.bounding-box {
background-image: url(...);
background-size: contain;
position: absolute;
background-position: center;
background-repeat: no-repeat;
height: 100%;
width: 100%;
}
