SVG in img element proportions not respected in ie9

Question

CSS:

img{     max-height:30px; } 

HTML:

<img src="foo.svg" /> 

I am looking for this svg image to scale proportionately to a max height of 30 pixels high. The natural dimensions of the svg are 200px by 200px. Works great in FF and Chrome (30x30) but in IE9 the image is 30x200. Now here is the kicker. It only happens with certain SVG files, other svgs scale correctly.

It seems the difference is one is made of polygons, and the other is made of paths.

does not scale correctly:

any idea on why this happens, or how I can get the first one to scale proportionately in ie9?

Answer 1

To get more consistent scaling across browsers always ensure you specify a viewBox but leave off the width and height attributes on your svg element. I've created a test page for comparing the effect of specifying the different SVG attributes in combination with widths and heights specified in CSS. Compare it side by side in a few different browsers and you'll see a lot of differences in the handling.

Answer 2

To fix it in ie9 and not to stuck with this. I don't know why, but you should set width:100% through css-rule, but not in img-tag. Aspect ratio will work by magic)) It helped me, hope this post will help other.
