How can we scale the svg when using custom svg ?

[weswes]

I've a custom svg file, and I would like the image to take the whole width on screen (see image below).

How can I do ?

Is the shape in the svg the same width as the svg root width, like: <svg width="_96_" height="_96_" and <rect height="_96_" width="_96_"
