SVG The SVG element viewBox
Example
The viewBox attribute defines the coordinate system for an <svg> element. This allows you to easily change the size and relative proportion of an SVG graphic without having to adjust the position and dimensions of every individual drawn element.
<!-- stretches a small icon to 60px square -->
<svg viewBox="0 0 16 16" height="60px" width="60px">
<path d="M16 6.216l-6.095-.02L7.98.38 6.095 6.196 0 6.215h.02l4.912 3.57-1.904 5.834h.02l4.972-3.59 4.932 3.59-1.904-5.815L16 6.215" />
</svg>
That code looks like this:
Without the viewBox, it looks like this:
