I would like to use em units to specify the size of SVG images in my pages. When the page is zoomed and the em value changes, I would like those diagrams to scale as well. Zooming the text on this page shows the div resizes whereas the SVG is always the same size (and not the full size initially).
I figured it out, CSS has to be used to do the em height. The size of the text though increases faster than the size of the image.
