+<p><code>viewBox</code>属性は、特定のcontainer要素に合わせるためのグラフィックス stretchのセットを指定できます。</p>
+
+<p>The value of the <code>viewBox</code> attribute is a list of four numbers <code>min-x</code>, <code>min-y</code>, <code>width</code> and <code>height</code>, separated by whitespace and/or a comma, which specify a rectangle in user space which should be mapped to the bounds of the viewport established by the given element, taking into account attribute {{ SVGAttr("preserveAspectRatio") }}.</p>
+
+<p>Negative values for <code>width</code> or <code>height</code> are not permitted and a value of zero disables rendering of the element.</p>
