如果你正在使用React与样式组件。我发现分离元素更简单。不是“神奇的解决方案”，但它确实有效。

import React from 'react';
import styled from "@emotion/styled";

const Container = styled.div`
  padding-top: 210px;
  padding-left: 50px;  
  display: inline-flex;
`

const Title1 = styled.div`
  position: absolute;
  font-size: 25px;
  left:40px;
  color: white;
  margin-top: -17px;
  padding-left: 40px;
`

const Title2 = styled.div`
  position: absolute;
  font-size: 25px;
  left:1090px;
  color: white;
  margin-top: -17px;
  padding-left: 40px;
`

const Line1 = styled.div`
  width: 20px;
  border: solid darkgray 1px;
  margin-right: 90px;
`
const Line2 = styled.div`
  width: 810px;
  border: solid darkgray 1px;
  margin-right: 126px;
`
const Line3 = styled.div`
  width: 178px;
  border: solid darkgray 1px;
`


const Titulos = () => {
    return (
        <Container>
            <Line1/>
            <Title1>
                FEATURED
            </Title1>
            <Line2/>
            <Line1/>
            <Title2>
                EXCLUSIVE
            </Title2>
            <Line3/>
        </Container>
    );
};

export default Titulos;

结果:

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/

   <div class="flex items-center">
      <div class="flex-grow bg bg-gray-300 h-0.5"></div>
      <div class="flex-grow-0 mx-5 text dark:text-white">or</div>
      <div class="flex-grow bg bg-gray-300 h-0.5"></div>
   </div>

使用Bootstrap 4预定义类

<div class="row align-items-center">
  <div class="col dropdown-divider"></div>
  <div class="col-auto">OR</div>
  <div class="col dropdown-divider"></div>
</div>

我已经尝试了大多数建议的方法，但结束了一些问题，如全宽度，或不适合动态内容。最后我修改了一个代码，并完美地工作。这个示例代码将在之前和之后绘制这些线条，并且在内容更改方面非常灵活。中心对齐。

HTML

        <div style="text-align:center"> 
            <h1>
                <span >S</span>
            </h1> 
        </div> 

        <div style="text-align:center"> 
            <h1>
                <span >Long text</span>
            </h1> 
        </div> 

CSS

      h1 {
            display: inline-block;
            position: relative;
            text-align: center;
        }

        h1 span {
            background: #fff;
            padding: 0 10px;
            position: relative;
            z-index: 1;
        }

        h1:before {
            background: #ddd;
            content: "";
            height: 1px;
            position: absolute;
            top: 50%;
            width: calc(100% + 50px);//Support in modern browsers
            left: -25px;
        }

        h1:before {
            left: ;
        }
