Question

我有一个容器，我想让h2看起来与中心对齐，后面有一条细线。我无法做到的是让这条线落在h2框后面。无论我尝试什么，它都会一直穿过超过 h2框。

以下是我需要完成的示例：

任何帮助表示感谢。

<div class="wrapper">
  <div class="section-header">
    <h2>H2 needs to be centered</h2>
    <div class="line-section-header"></div>
  </div>
</div>

我使用的CSS是：

h2 {
    font-family: 'Open Sans', Arial, sans-serif;
    font-family: 20px;
    font-weight: 700;
    text-transform: uppercase;
    width: 140px;
    color: #3F3F3F;
    background-color: white;
    padding: 5px 10px;
    border: 1px solid #D3D3D3;
    text-align: center;
    margin: 0 auto;
    z-index: 999;
}


.wrapper {
    margin: 0 auto;
    width: 980px;
    height: 1000px;
    background-color: #white;
}

.section-header {
    width: 100%;
    height: auto;
    background-color: white;
    float: left;
    position: relative;
}

.line-section-header {
    width: 100%;
    height: 1px;
    background-color: #D3D3D3;
    margin-top: 15px;
    position: absolute;
}

HTML

<div class="container">

  <h2>  h2 </h2>
  <div class="line"> </div>

</div>

CSS

  position:absolute;
  width:100%;
  height: 1px;
  background: red;
  top:50%;
  margin:1px 0px;  
  z-index:-9;

}

h2 {//其他道具位置：相对; }

Answer 3

对齐将是动态的容器高度

.wrapper {
    margin: 0 auto;
    width: 980px;
    height: 1000px;
    background-color: #white;
}

.section-header {
    width: 100%;
    height: auto;
    background-color: white;
    float: left;
    position: relative;
}

h2 {
    font-family: 'Open Sans', Arial, sans-serif;
    font-family: 20px;
    font-weight: 700;
    text-transform: uppercase;
    width: 140px;
    color: #3F3F3F;
    background-color: white;
    padding: 5px 10px;
    border: 1px solid #D3D3D3;
    text-align: center;
    margin: 0 auto;
    z-index: 999;
    position: relative;
}
.line-section-header {
    width: 100%;
    height: 1px;
    background-color: #D3D3D3;
    top: 50%;
    position: absolute;
    z-index: 1;
}

<div class="wrapper">
  <div class="section-header">
    <h2>H2 needs to be centered</h2>
    <div class="line-section-header"></div>
  </div>
</div>

Answer 4

尝试添加此内容：

h2 {
  position: absolute;
  left:0;
  right:0;
  margin:auto;
}

.line-section-header {
  margin-top: 50px;
  position: absolute;
}

Answer 5

尝试在css中更改此内容：

h2 {
    font-family: 'Open Sans', Arial, sans-serif;
    font-family: 20px;
    font-weight: 700;
    text-transform: uppercase;
    width: 140px;
    color: #3F3F3F;
    background-color: white;
    padding: 5px 10px;
    border: 1px solid #D3D3D3;
    text-align: center;
    margin: 0 auto;
    margin-left: 420px;
    z-index: 2;
    position: absolute;
}


.wrapper {
    margin: 0 auto;
    width: 980px;
    height: 1000px;
    background-color: #white;
    position: relative;
}

.section-header {
    width: 100%;
    height: auto;
    background-color: white;
    float: left;
    position: relative;
}

.line-section-header {
    width: 100%;
    height: 1px;
    background-color: #D3D3D3;
    margin-top: 70px;
    position: absolute;
    z-index: 1;
}

Z-index定位不正常
