Resizing SVG in html?

Try these:

1. Set the missing viewbox and fill in the height and width values of the set height and height attributes in the svg tag

2. Then scale the picture simply by setting the height and width to the desired percent values. Good luck.

3. Set a fixed aspect ratio with preserveAspectRatio="X200Y200 meet (e.g. 200px), but it's not necessary

e.g.

 <svg
   xmlns:dc="http://purl.org/dc/elements/1.1/"
   xmlns:cc="http://creativecommons.org/ns#"
   xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
   xmlns:svg="http://www.w3.org/2000/svg"
   xmlns="http://www.w3.org/2000/svg"
   xmlns:xlink="http://www.w3.org/1999/xlink"
   xmlns:sodipodi="http://sodipodi.sourceforge.net/DTD/sodipodi-0.dtd"
   xmlns:inkscape="http://www.inkscape.org/namespaces/inkscape"
   width="10%" 
   height="10%"
   preserveAspectRatio="x200Y200 meet"
   viewBox="0 0 350 350"
   id="svg2"
   version="1.1"
   inkscape:version="0.48.0 r9654"
   sodipodi:docname="namesvg.svg">

Open your .svg file with a text editor (it's just XML), and look for something like this at the top:

<svg ... width="50px" height="50px"...

Erase width and height attributes; the defaults are 100%, so it should stretch to whatever the container allows it.
