SVG CSS Multiple animations

svg

I have created a treasure map animation, first, it will display the path in light grey but as animation begins I would like the light grey dashes to disappear or turn to a black color as the fill animation ".road" kicks in. I am struggling to get the light grey dashes ".steps" to disappear as the fill animations go over that position.

svg {
  position: absolute;
  top: 0;
  right: 0;
  bottom: 0;
  left: 0;
  margin: auto;
}

.road {
  stroke-dasharray: 744;
  stroke-dashoffset: -744;
  animation: draw-road 10s infinite;
}

.steps {
  stroke-dasharray: -744;
  stroke-dashoffset: 744;
  animation: draw-steps 10s reverse;
}

@keyframes draw-road {
  0% {
    stroke-dashoffset: 744;
    stroke: #000000;
  }
  100% {
    stroke-dashoffset: 0;
    stroke: #000000;
  }
}

@keyframes draw-steps {
  0% {
    stroke-dashoffset: 0;
  }
  100% {
    stroke-dashoffset: 0;
  }
}

Solution using SVG mask.

  • Below is a black line class="road"
  • Above is a gray line class="steps"
  • A mask is applied to the gray line which, when moving, erases the gray line showing the black line

This creates the effect of filling the gray line with black

svg{
  position:absolute;
  top:0;
  right:0;
  bottom:0;
  left:0;
  margin:auto;
} 

.road{
  fill:none;
  stroke:black;
  stroke-dasharray:10 10;
  stroke-dashoffset:0;
  stroke-width:2;
}
.steps{
   fill:none;
   stroke:#999;
  stroke-dasharray:10 10;
  stroke-dashoffset:0;
  stroke-width:2;
  animation: draw-steps 10s reverse;
  
}

#stepMask{
   fill:none;
   stroke:black;
   stroke-width:2;
   stroke-dashoffset: 744;
   stroke-dasharray:744,744;
 
  
}
