Question

我想创建一个圆形条，当它前进时，它会变得更粗是否可以使用可以在离子移动应用程序上运行的css或svg。

这是我想要实现的目标：

以下是fiddle的起点：

＆＃13;

.wrap {
  background: #0b1626;
  padding: 2em;
  color: #FFF;
  font-family: 'Arial Black';
}
.knob {
  position: relative;
  margin: 0 auto;
  padding: 1.5em;
  width: 220px;
  height: 220px;
  border-radius: 50%;
  border: 1px solid #e84d51;
}
.knob .val {
  padding-top: 1em;
  font-size: 28px;
  text-align: center;
}

＆＃13;

<div class="wrap">
  <div class="knob">
    <div class="stats">
      <p class="val">16,858<br>1,285</p>
    </div>
  </div>
</div>

＆＃13;

这是我的尝试。有很多div，但我没有时间尝试减少它们。

基本上，它会在一个圆圈和另一个圆圈之间进行偏移。

.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>

顺便说一句，关于在div中实现底层形状的一个例子，使用边框和伪元素

.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>
