SVG circle not appearing in HTML CSS

Question

I am creating a really simple loader page for my application. I wanted to use a circle, that rotates, and as I saw a tutorial, I used the SVG and circle tags. Here is the code HTML:

<div className="loader">
      <svg className="svg">
        <circle cx="70" cy="70" height="100px" width="100px" />
      </svg>
   </div>

And here is all the involved CSS in this case:

.loader{
  display: flex;
  justify-content: center;
  align-items: center;
  min-height: 100vh;
}

.svg{
  width: 150px;
  height: 150px;
  animation: rotate 2s linear infinite;
}

@keyframes rotate{
  0%{
    transform: rotate(0deg);
  }
  100%{
    transform: rotate(360deg);
  }
}

.svg circle{
  background-color: red;
  width: 1em;
  height: 1em;
  fill: var(--redwine);
  stroke-width: 10;
  stroke: var(--redwine);
  stroke-linecap: round;
  transform:translate(5px, 5px);
  stroke-dasharray: 440;
  stroke-dashoffset: 440;
  animation: circular 4s linear infinite;
  z-index: 100;
}

@keyframes circular{
  0%, 100%{
    stroke-dashoffset: 440;
  }
  50%{
    stroke-dashoffset: 0;
  }
  50.1%{
    stroke-dashoffset: 880;
  }
}

The only problem with all this code is that whenever I open the page, to see if all is working, it gives me an empty page. So I try to inspect. When I hover in the browser the code of SVG, it shows the shadow of a square that rotates, but when I hover the circle code, it shows a point with the following label: circle 0x0 . I think that it is not rendering correctly, or I am blocking it. I don't really know.

Can someone help? Thank you a lot

You are missing the radius attribute r .

<circle cx="70" cy="70" r="25" height="100px" width="100px" />

See below:

 .loader { display: flex; justify-content: center; align-items: center; min-height: 100vh; }.svg { width: 150px; height: 150px; animation: rotate 2s linear infinite; } @keyframes rotate { 0% { transform: rotate(0deg); } 100% { transform: rotate(360deg); } }.svg circle { background-color: red; width: 1em; height: 1em; fill: var(--redwine); stroke-width: 10; stroke: var(--redwine); stroke-linecap: round; transform: translate(5px, 5px); stroke-dasharray: 440; stroke-dashoffset: 440; animation: circular 4s linear infinite; z-index: 100; } @keyframes circular { 0%, 100% { stroke-dashoffset: 440; } 50% { stroke-dashoffset: 0; } 50.1% { stroke-dashoffset: 880; } }

 <div className="loader"> <svg className="svg"> <circle cx="70" cy="70" r="25" height="100px" width="100px" /> </svg> </div>
