Clip-path doesn't work in firefox [% values]

Question

I am trying to run svg clip-path in mozilla but it doesn't work.

.mask-1 {
    -webkit-clip-path: polygon(0% 0%, 58% 0%, 39% 81.8%, 0% 81.8%);
    clip-path: polygon(0% 0%, 58% 0%, 39% 81.8%, 0% 81.8%);
}

It works in chrome perfectly. Can anyone can help me out with mozilla and other browsers?

Answer 1

You can use an inline SVG (as the code below shows) in Firefox, where your points are the percentage / 100. Because of the attribute clipPathUnits the mask will be responsive.

<svg width="0" height="0">
  <defs>
    <clipPath id="clip-shape" clipPathUnits="objectBoundingBox">
      <polygon points="0 0, 0.58 0, 0.39 0.818, 0 0.818" />
    </clipPath>
  </defs>
</svg>

Refer to the svg like

.mask-1 {
   -webkit-clip-path: polygon(0% 0%, 58% 0%, 39% 81.8%, 0% 81.8%);
   clip-path: polygon(0% 0%, 58% 0%, 39% 81.8%, 0% 81.8%);
   -webkit-clip-path: url("#clip-shape"); 
   clip-path: url("#clip-shape");
}

I struggled extensively with this, since my svg was dynamically added to the page. Applying the clip-path css-property with a delay (or pageload) via js solved my problems in FF.

There is no support in IE by my knowledge.
