title: How can I create a "glow" around a rectangle with svg?
body: <p>I have something like the following:</p>
  
  <pre><code>&lt;svg id="svgLogo1" style="left:0; top:0; position:absolute"
          width="980" height="80" viewBox="0 0 980 80" 
          xmlns="http://www.w3.org/2000/svg"&gt;
      &lt;rect x="0" y="5" width="980" height="54" rx="6" ry="6" 
              style="stroke-width:2; xstroke:#FFF; fill:#555"/&gt;
  &lt;/svg&gt;
  </code></pre>
  
  <p>I would like to create a white glow around this. </p>
  
  <p>Is there some way that I can do this in svg. I looked around and all I can find is "shadow" which is not really what I am looking for as I want a shadow (Glow) around all four sides of the rectangle.</p>
