我使用一个表格布局来动态填充边和0高度，绝对位置div动态垂直定位:

没有硬编码的维度 没有图像 没有它 方面的背景 控制条外观

https://jsfiddle.net/eq5gz5xL/18/

我发现，稍微低于真中心的文字效果最好;这可以在55%的位置进行调整(身高越高，界限越低)。线条的外观可以改变边界底部的位置。

HTML:

<div class="title">
  <div class="title-row">
    <div class="bar-container">
      <div class="bar"></div>
    </div>
    <div class="text">
      Title
    </div>
    <div class="bar-container">
      <div class="bar"></div>
    </div>
  </div>
</div>

CSS:

.title{
  display: table;
  width: 100%
  background: linear-gradient(to right, white, lightgray);
}
.title-row{
  display: table-row;
}
.bar-container {
  display: table-cell;
  position: relative;
  width: 50%;
}
.bar {
  position: absolute;
  width: 100%;
  top: 55%;
  border-bottom: 1px solid black;
}
.text {
  display: table-cell;
  padding-left: 5px;
  padding-right: 5px;
  font-size: 36px;
}

好吧，这个更复杂，但它适用于所有浏览器，除了IE<8

<div><span>text TEXT</span></div>

div {
    text-align: center;
    position: relative;
}
span {
    display: inline-block;    
}
span:before,
span:after {
    border-top: 1px solid black;
    display: block;
    height: 1px;
    content: " ";
    width: 40%;
    position: absolute;
    left: 0;
    top: 1.2em;
}
span:after {
   right: 0;  
   left: auto; 
}

:before和:after元素的位置是绝对的，因此我们可以将一个元素拉到左边，一个元素拉到右边。此外，宽度(在本例中为40%)非常依赖于内部文本的宽度。我得想个解决办法。至少在顶部:1.2em可以确保即使字体大小不同，线条也或多或少地保持在文本的中心。

它似乎工作得很好:http://jsfiddle.net/tUGrf/3/

使用Flexbox的简单方法

# title-wrapper { 显示:flex; 对齐项目:中心; ｝ .title { flex-wrap:包装; Margin: 0 10px 0 10px; text-align:中心; ｝ .line { flex: 1; 身高:1 px; 背景颜色:黑色; ｝ <节id =“title-wrapper”> < div class = '行' > < / div > <div class='title'>some text</div> < div class = '行' > < / div > < / >节

下面是我对Bootstrap 5的简单解决方案，只使用预定义的类:

<div class="py-3 d-flex align-items-center">
    <hr class="flex-grow-1" />
    <div class="badge bg-secondary">OR</div>
    <hr class="flex-grow-1" />
</div>

结果:

你可以将它作为React组件重用，例如:

export default function Divider({ text }) {
    return <div className="py-3 d-flex align-items-center">
        <hr className="flex-grow-1" />
        <div className="badge bg-secondary">{ text }</div>
        <hr className="flex-grow-1" />
    </div>;
}
