Make SVG path take full width and height of screen

Question

I have an inline SVG path that animates a dash to look like the snake game. Now my question is how to get this path to take up the full width and height of the screen and act responsive if the screen goes smaller or bigger.

HTML

<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="100%" height="100%" viewBox="0 0 659 522" enable-background="new 0 0 659 522" xml:space="preserve">
    <path class="path" width="100%" height="100%" fill="none" stroke="#00ff00" stroke-width="5" stroke-miterlimit="10" d="M656.5,2.5v517H2.5V2.5H656.5z"
    stroke-dasharray="2042 300"
    stroke-dashoffset="2342" />
</svg>

CSS

.path {
    animation: dash 10s linear infinite;
}

@-webkit-keyframes dash {
    to {
        stroke-dashoffset: 0;
    }
}

Here is a fiddle with the code I have.

Answer 1

You have to tell the SVG not to maintain its aspect ratio with preserveAspectRatio="none" in the SVG code..then it's just CSS.

JSfiddle Demo

html,
body {
  margin: 0;
  height: 100%;
}
svg {
  display: block;
}
.path {
  animation: dash 10s linear infinite;
}
@-webkit-keyframes dash {
  to {
    stroke-dashoffset: 0;
  }
}

<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" width="100%" height="100%" viewBox="0 0 659 522" enable-background="new 0 0 659 522" xml:space="preserve" preserveAspectRatio="none">
  <path class="path" width="100%" height="100%" fill="none" stroke="#00ff00" stroke-width="5" stroke-miterlimit="10" d="M656.5,2.5v517H2.5V2.5H656.5z" stroke-dasharray="2042 300" stroke-dashoffset="2342" />
</svg>
