CSS radial gradient to SVG radial gradient

Question

Is it possible to make a radial gradient in SVG, like in CSS http://codepen.io/A973C/pen/hnEaf (I mean the lights in the traffic light)

.red{
  background: red;
  background-image: radial-gradient(brown, transparent);
  background-size: 15px 15px; 
  width: 100px;
  height: 100px;
  border-radius: 50%;
  position: absolute;
  top: 20px;
  left: 35px;
  animation: 13s red infinite;
  border: dotted 2px red;
  box-shadow: 
    0 0 20px #111 inset,
    0 0 10px red;
}

My SVG gradient looks like this http://jsfiddle.net/x9a2Lyx1/ I really don't understand how to repeat the gradient like in the css example

Answer 1

SVG elements embedded in web pages are treated the same as any other element, so you only need to use CSS to achieve:

svg {
  background: green;
  background-image: radial-gradient(lime, transparent);
  background-size: 3px 3px;
  width: 100px;
  height: 100px;
  border-radius: 50%;
  border: dotted 2px lime;
  box-shadow: 
    0 0 20px #111 inset,
    0 0 10px lime;
}

<svg width="120" height="120" 
     xmlns="http://www.w3.org/2000/svg" version="1.1"
     xmlns:xlink="http://www.w3.org/1999/xlink">       
</svg>

I solved this problem using SVG pattern -> http://jsfiddle.net/k5527kym/

<pattern id="muster_c" patternUnits="userSpaceOnUse" width="2" height="2" x="0" y="0">
        <circle cx="1" cy="1" r="2" fill="url(#MyGradient)"/>
</pattern>
