<svg 
                id="logo"
                width="39" height="43" viewBox="0 0 39 43" fill="none" xmlns="http://www.w3.org/2000/svg">
                <g filter="url(#filter0_d)">

Here is my CSS code:

---

body {
  font-family: 'Nunito', sans-serif;
  width: 100%;
  height: 100vh;
}

#logo{
    position: absolute;
    top: 40%;
    left: 50%;
    transform: translate(-50%, -50%);
}

#logo path:nth-child(1){
    stroke-dasharray: 200px;
    stroke-dasharray: 50px;
}

Answer 1

I'n not very sure if this is what you are asking. This is what I was commenting:

Outside the filtered group I'm adding a use element: <use xlink:href="#a" id="theUse" /> . In the css I'm using the styles you are giving to the #logo path:nth-child(1)

 body { font-family: 'Nunito', sans-serif; width: 100%; height: 100vh; } #logo{ position: absolute; top: 40%; left: 50%; transform: translate(-50%, -50%); } #theUse{ stroke:silver; /*stroke-dasharray: 200px;*/ stroke-dasharray: 50px; }

 <svg id="logo" width="200" viewBox="0 0 39 43" fill="none" xmlns="http://www.w3.org/2000/svg"> <g filter="url(#filter0_d)"> <path id="a" d="M26.8047 26.0938H12.5078L9.29688 35H4.65625L17.6875 0.875H21.625L34.6797 35H30.0625L26.8047 26.0938ZM13.8672 22.3906H25.4688L19.6562 6.42969L13.8672 22.3906Z" fill="white" /> </g> <use xlink:href="#a" id="theUse" /> <defs> <filter id="filter0_d" x="0.65625" y="0.875" width="38.0234" height="42.125" filterUnits="userSpaceOnUse" color-interpolation-filters="sRGB"> <feFlood flood-opacity="0" result="BackgroundImageFix" /> <feColorMatrix in="SourceAlpha" type="matrix" values="0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 127 0" /> <feOffset dy="4" /> <feGaussianBlur stdDeviation="2" /> <feColorMatrix type="matrix" values="0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0.25 0" /> <feBlend mode="normal" in2="BackgroundImageFix" result="effect1_dropShadow" /> <feBlend mode="normal" in="SourceGraphic" in2="effect1_dropShadow" result="shape" /> </filter> </defs> </svg>
