So I've got an SVG shape that I'm animating using GSAP, and you can find it in this

I've tried using CSS Blendmodes, like so:

line {
  mix-blend-mode: screen;
}

Is there any way I'm able to do this? Either with CSS or with JavaScript?

CodePudding user response：

I don't know React, so this may collide with your further plans, but you could just mask it out in SVG. You put the circle over the lines, but remove the part that covers them using a mask. Then you put another circle, white, behind the pink circle but still over the lines. This circle is then visible through the removed parts of the pink circle, so it looks as if the lines were turning white.

This, however, requires a reorganisation of the SVG:

(CodePen with your animation here)

        <!-- the circle with lines masked out, so the background circle 
          is visible through lines' area -->
