SVG path:nth-child-CodePudding

I am trying to make a SVG animation with text. trying to make dash array with the stroke but it is not working. I'm assuming that I have spelled something wrong but I can not find it.

* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
}

body {
  background-color: rgb(32, 35, 48);
  text-aline: center;
}

#logo {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, 50%);
}

#logo path:nth-child(1) {
  stroke-dasharray: 30px;
}

#logo path:nth-child(2) {}

#logo path:nth-child(3) {}

#logo path:nth-child(4) {}

#logo path:nth-child(5) {}

#logo path:nth-child(6) {}

#logo path:nth-child(7) {}

#logo path:nth-child(8) {}

There's no problem with the spelling of stroke-dasharray. Your CSS selection is what's causing the problem.

The CSS selector: #logo path:nth-chidl(1) is targeting the first path inside the <mask>, instead of the path outside the mask.

Maybe you can wrap your letters (path elements outside of the mask) in a g.letters and apply the following CSS selector:

#logo > g.letters > path:nth-child(1) {
  stroke-dasharray: 30px;
}

As @Michael Mullany commented:

I don't understand why you're using a mask rather than setting stroke-dasharray directly on the shapes.

Thanks Michael for the advice, that's what I did.

To animate the outline of the letters, I use changing the stroke-dashoffset attribute from maximum to zero.

* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
}

body {
  background-color: rgb(32, 35, 48);
  
}

#logo {
  position: absolute;
  top: 50%;
  left: 50%;
  transform: translate(-50%, 50%);
}

.letter {
  stroke:white;
  stroke-width:5px;
  stroke-dasharray: 30 10;
  stroke-dashoffset:400;
  animation : dash 6s linear infinite;
}

@keyframes dash {
0%{stroke-dashoffset:400;}
100%{stroke-dashoffset:0;}
}
