  position: relative;
  margin: 0 auto;
  padding: 1.5em;
  width: 220px;

    </div>
  </div>
</div>

Answer 1

Here is my attempt. There is a lot of divs, but I didn't had the time to try to reduce them.

Basically, it plays with offsets between one circle and the other.

.container {
  width: 400px;
  height: 400px;
  position: relative;
  background-color: black;
}

.left {
  position: absolute;
  width: 50%;
  height: 100%;
  right: 0px;
  overflow: hidden;
}

.moving {
  animation: rotatel 8s 1s linear forwards; /* to keep both animations the same */
}

.left .moving {
  position: absolute;
  width: calc(200% - 70px);
  height: calc(100% - 70px);
  right: 15px;
  top: 20px;
  border: 20px solid transparent;
  border-top-color: red;
  border-right-color: red;
  border-radius: 50%;
  transform: rotate(-135deg);
}

@keyframes rotatel {
   from {transform: rotate(-135deg);}
   50%, 100% {transform: rotate(45deg);}
}

.right {
  position: absolute;
  width: 50%;
  height: 100%;
  left: 0px;
  overflow: hidden;
}

.right .moving {
  position: absolute;
  width: calc(200% - 50px);
  height: calc(100% - 50px);
  left: 10px;
  top: 0px;
  border: 20px solid transparent;
  border-top-color: red;
  border-right-color: red;
  border-radius: 50%;
  transform: rotate(45deg);
  animation-name: rotater;
}

@keyframes rotater {
   0%, 50% {transform: rotate(45deg);}
   100% {transform: rotate(225deg);}
}
.inner {
  position: absolute;
  width: calc(100% - 40px);
  height: calc(100% - 40px);
  border-radius: 50%;
  background-color: white;
  left: 20px;
  top: 20px;
  border: red solid 1px;
  background-color: black;
}

<div class="container">
<div class="left">
    <div class="moving"></div>
</div>
<div class="right">
    <div class="moving"></div>
</div>
<div class="inner"></div>
</div>

As an aside, an exmple about achieving the underlying shape in a div, using borders an a pseudoelement

.test1 {
  width: 400px;
  height: 400px;
  border: 1px solid red;
  border-top-width: 1px;
  border-right-width: 10px;
  border-bottom-width: 20px;
  border-left-width: 30px;
  border-radius: 50%;
  position: relative;
  margin: 40px;
}

.test1:after {
  content: "";
  position: absolute;
  width: 50%;
  height: 50%;
  border: 0px solid green;
  border-left-width: 30px;
  border-top-width: 40px;
  border-radius: 100% 0px 0px 0px;
  position: absolute;
  top: -40px;
  left: -30px;
}

<div class="test1"></div>
