css - 如何保持具有动态内容的元素的圆形形状？

Question

我正在尝试创建一个圆圈作为 ::after伪元素，根据其内容自动调整大小。

.container {
    display: flex;
    flex-direction: row;
}

#dividerHost2 #left {
    flex: 1 1 auto;
    background-color: yellowgreen;
    height: 200px;
}

#dividerHost2 #right {
    flex: 1 1 auto;
    background-color: dodgerblue;
}

#dividerHost2 .divider {
    background-color: white;
    margin: 0px;
    width: 6px;
    font-weight: 800;
}

.divider.vertical {
    --divider-color: transparent;
    display: inline-flex;

    width: 1px;
    border-left: 1px solid rgb(var(--divider-color));
    margin: 0px 2px 0px 2px;
    overflow: show;
}

.divider.vertical.title::after {
    flex: 0 0 auto;
    align-self: center;
    border-radius: 50%;
    content: "OR";
    padding: 9px 8px 11px 8px;
    background-color: white;
    color: black;

    transform: translateX(-44%);
    z-index: 10;
}

<div id="dividerHost2" class="container">
  <div id="left" class="container" style="flex-direction: row;"></div>
  <div id="divider3" class="divider vertical title"></div>
  <div id="right" class="container" style="flex-direction: row;"></div>
</div>

到目前为止，这给出了一个非常好的结果:

但是，对于较长的文本，圆圈会变成椭圆形:



如何使圆圈根据其内容自动调整大小？

Answer 1

这是使用径向梯度的技巧。这个想法是保持元素全高并使用 circle closest-side 为它着色这将始终创建一个圆，该圆将从中心开始并扩展到最近的两侧(左侧和右侧)

我简化了代码以仅保留相关部分:

.container {
  display: flex;
  flex-direction: row;
  margin:10px;
}

.left {
  flex: 1 1 auto;
  background-color: yellowgreen;
  height: 200px;
}

.right {
  flex: 1 1 auto;
  background-color: dodgerblue;
}

.divider {
  background-color: white;
  width: 6px;
  font-weight: 800;
  display: flex;
  justify-content: center;
}

.divider::after {
  display: flex;
  align-items: center;
  flex: 0 0 auto;
  content: attr(data-text);
  padding: 0 8px;
  background: radial-gradient(circle closest-side, white 98%, transparent 100%);
  z-index: 10;
}

<div  class="container">
  <div class="left "></div>
  <div class="divider" data-text="OR"></div>
  <div class="right "></div>
</div>

<div class="container">
  <div class="left "></div>
  <div class="divider" data-text="longer"></div>
  <div class="right "></div>
</div>

<div class="container">
  <div class="left "></div>
  <div class="divider" data-text="even longer"></div>
  <div class="right "></div>
</div>
