如何保持具有动态含量的元素的圆形形状? [英] How to maintain a circlur shape of element with dynamic content?

问题描述

我正在尝试创建一个圆形，作为 :: after 伪元素，该伪元素会根据其内容自动调整大小.

  .container {显示:flex;flex-direction:行；}#dividerHost2 #left {flex:1 1自动;背景颜色:黄绿色；高度:200px；}#dividerHost2 #right {flex:1 1自动;背景颜色:dodgerblue;}#dividerHost2 .divider {背景颜色:白色；边距:0px;宽度:6像素；字体粗细:800；}.divider.vertical {--divider-color:透明;显示:inline-flex;宽度:1px；左边框:1像素实心rgb(var(-divider-color));边距:0px 2px 0px 2px;溢出:显示；}.divider.vertical.title ::之后{flex:0 0自动;自我定位:居中；边界半径:50％；内容:或"；填充:9px 8px 11px 8px;背景颜色:白色；颜色:黑色;转换:translateX(-44％);z索引:10；}  

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

到目前为止，这给出了一个非常不错的结果:

如何根据其内容自动调整圆的大小?

解决方案

以下是使用径向渐变的技巧.想法是保持元素全高并使用 circle最近面对其进行着色，这将始终创建一个从中心开始并扩展到最接近的侧面(左右两边)的圆

我简化了代码，只保留了相关部分:

  .container {显示:flex;flex-direction:行；边距:10px;}.剩下 {flex:1 1自动;背景颜色:黄绿色；高度:200px；}.正确的 {flex:1 1自动;背景颜色:dodgerblue;}.divider {背景颜色:白色；宽度:6像素；字体粗细:800；显示:flex;证明内容:中心；}.divider ::之后{显示:flex;align-items:居中;flex:0 0自动;内容:attr(数据文本);填充:0 8px;背景:放射状渐变(圆形最近侧，白色98％，透明100％)；z索引: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 =甚至更长"></div>< div class ="right"></div></div>  

I'm trying to create a circle as an ::after pseudo element, which resizes automatically depending on its content.

.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>

That gives a pretty nice result so far:

However, with longer text the circle turns into an oval:

How to make the circle auto resize depending on its content?

解决方案

Here is a trick using radial-gradient. The idea is to keep the element full height and color it using circle closest-side which will always create a circle that will start from the center and expand to the closest sides (left and right one)

I simplified the code to keep only the relevant part:

.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>
