SVG Fill Animation doesn't work on Firefox and Edge

Question

I have a simple animation where an SVG fills on mouse over. It is working fine on Chrome, but I've found that it's doesn't workg on Firefox or Edge. I've tried few different approaches, but nothing seems to help. I'm new to SVG and I guess I'm missing something? What is the proper way to achieve what I'm trying to do? Here is the code:

svg#bogeLogo {
  display: block;
  left: 50%;
  position: absolute;
  top: 50%;
  transform: translate(-50%,-50%);
}

svg#bogeLogo #bogePath {
  fill: transparent;
  stroke: red;
  stroke-width: 8;
}

svg#bogeLogo #bogeFinal {
  fill: blue;
}

svg#bogeLogo #bogeClip rect {
  transition: all 1.4s ease-out !important;
  width: 0;
}

svg#bogeLogo:hover #bogeClip rect {
  width: 100%;
}

Answer 1

Modifying geometric attributes, such as width, is a new thing in SVG 2. Only Chrome has implemented that so far.

You will need to use a different method to animate your <rect>. For example, you could move it horizontally using a transform, instead of changing its width.

Update

It looks like there is a bug in Firefox at the moment, causing CSS selectors to not match elements in the <defs> section.

The solution is to use the logo as the clippath, and move a blue rectangle in and out instead.

svg#bogeLogo {
  display: block;
  left: 50%;
  position: absolute;
  top: 50%;
  transform: translate(-50%,-50%);
}

#bogePath {
  fill: transparent;
  stroke: red;
  stroke-width: 8;
}

svg#bogeLogo #bogeFinal {
  fill: blue;
  transition: all 1.4s ease-out !important;
  transform: translateX(-2552px);
}

svg#bogeLogo:hover #bogeFinal {
  transform: translateX(0px);
}
