How to auto resize the image for responsive design with pure css?

Question

I have tried to auto resize the image using the CSS property max-width, but it does't work in IE7 and IE8. Is there any way to auto resize the image with pure CSS in IE7 and IE8?

Answer 1

Use width: inherit; to make it work with pure CSS in IE8. (See responsive-base.css.) Like this:

img {
  width: inherit;  /* This makes the next two lines work in IE8. */
  max-width: 100%; /* Add !important if needed. */
  height: auto;    /* Add !important if needed. */
}

I'm not sure if that works in IE7—please test it and let us know if you're testing IE7. Before I figured out the width: inherit technique I was using the jQuery below, so you could try it if you really need support down to IE7 and the first technique doesn't work:

<!--[if lt IE 9]><script>
jQuery(function($) {
    $('img').each(function(){
        // .removeAttr supports SSVs in jQuery 1.7+
        $(this).removeAttr('width height');
    });
});
</script><![endif]-->

Try something like this:

width: expression(document.body.clientWidth > 800 ? "800px" : "auto" );

/* If page is wider than 800px then set width to 800px, otherwise set to auto */

You need a one-time cached expression for IE 6-7.

IMG {
zoom:expression(
    function(t){
        t.runtimeStyle.zoom = 1;
        var maxW = parseInt(t.currentStyle['max-width'], 10);
        var maxH = parseInt(t.currentStyle['max-height'], 10);
        if (t.scrollWidth > maxW && t.scrollWidth >= t.scrollHeight) {
            t.style.width = maxW;
        } else if (t.scrollHeight > maxH) {
            t.style.height = maxH;
        }
    }(this)
);
}
