CSS Animating SVG with CSS Keyframe and Line Drawing Animations Animating stroke-dasharray and stroke-dashoffset

Trying to Use Javascript to Initialize Array & Offset. Why is it Not Working?

I decided to use a transition instead of keyframes. The animation starts immediately when it's supposed to wait for hover, & instead of starting hidden & drawing itself it starts drawn & erases itself. Here is the Mediafire link.

The "animation" you see initially is just the initial offset being established by the transition. I found the following issues with the other functionality:

  • The CSS needs to know the initial dashoffset, so it can perform the transition on hover (and return after).
  • "Path" apparently has no physical presence of its own, so it can't be a hover target (but the SVG can be).
  • Since the length had to be added to the CSS anyway, I eliminated the JavaScript code entirely.
partial-style.css 
path {
  stroke-dasharray: 71px;
  stroke-dashoffset: 71px;   /* <-- initial offset is established here */
  transition: stroke-dashoffset 1s linear;
}
svg:hover path {             /* <-- svg is the hover target (path is still the rule target) */
  stroke-dashoffset: 0; */
}

After all this, I'm not sure if this is what you really want, since the offset position returns when the mouse goes away from the SVG. If you want a one-time animation, then you'll want to go back to using keyframe animation.
