title: Default background color of SVG root element
body: <p>I'd like to set a default background color for the entire SVG document, to red for example.</p>
  
  <pre><code>&lt;svg viewBox="0 0 500 600" style="background: red"&gt;/* content */&lt;/svg&gt;
  </code></pre>
  
  <p>The solution above works but the background property of the style attribute is unfortunately not a standard one : <a href="http://www.w3.org/TR/SVG/styling.html#SVGStylingProperties">http://www.w3.org/TR/SVG/styling.html#SVGStylingProperties</a>, and so it gets removed during the cleaning process with SVG Cleaner.</p>
  
  <p>Is there another way to declare this background color?</p>
