CSS 只旋转边框

Question

我想制作三个围绕文本旋转的圆形微调器，这些微调器中的文本将保持静止。

我只能通过参考 Bootstrap 中的 .spinner-border 来使用 CSS 执行此操作。无法修改 HTML 文件。

.loader-wrapper {
  position: fixed;
  width: 100%;
  height: 100%;
  text-align: center;
  z-index: 1;
}

@-webkit-keyframes spinner-border {
  to {
    -webkit-transform: rotate(360deg);
    transform: rotate(360deg);
  }
}

@keyframes spinner-border {
  to {
    -webkit-transform: rotate(360deg);
    transform: rotate(360deg);
  }
}

.loader {
  position: relative;
  left: auto;
  top: auto;
  width: 80px;
  font-size: 20px;
  text-align: center;
  display: inline-block;
  width: 10rem;
  height: 10rem;
  vertical-align: text-center;
  border: 0.25em solid currentColor;
  border-right-color: transparent;
  border-radius: 50%;
  -webkit-animation: spinner-border .75s linear infinite;
  animation: spinner-border .75s linear infinite;
}

<div class="loader-wrapper">
  <div class="loader">Loading</div>
</div>

我试过先做一个微调器。但我不知道如何让文字保持静止。

.loader-wrapper {
  position: fixed;
  width: 100%;
  height: 100%;
  text-align: center;
  z-index: 1;
}

@-webkit-keyframes spinner-border {
  to {
    -webkit-transform: rotate(360deg);
    transform: rotate(360deg);
  }
}

@keyframes spinner-border {
  to {
    -webkit-transform: rotate(360deg);
    transform: rotate(360deg);
  }
}

.loader {
  position: relative;
  top: 5px;
  left: auto;
  width: 80px;
  font-size: 20px;
  text-align: center;
  display: inline-block;
  width: 10rem;
  height: 10rem;
  vertical-align: text-center;
  
}
.loader::after {
  content: '';
  position: absolute;
  left: 0;
  top: -10px;
  width: 100%;
  height: 100%;
  border: 0.25em solid currentColor;
  border-right-color: transparent;
  border-radius: 50%;
  -webkit-animation: spinner-border .75s linear infinite;
  animation: spinner-border .75s linear infinite;
}

<div class="loader-wrapper">
  <div class="loader">Loading</div>
</div>
