如何将<div> div中的两个<hero>居中？ Here is my codepen

为了让事情更加清晰，我想要拍摄我的照片和背景图像中央的灰色矩形形状。

HTML 

<div class="hero">
  <div class="shape"></div>
  <div class="shape2">
      <p>kjjjjjjjjjkjjjkkjkj</p>
  </div>
</div>

CSS 

.hero {
  background-image: url("https://static.pexels.com/photos/48727/pexels-photo-48727.jpeg");
  background-attachment: fixed;
  position:relative;
  width: 100%;
  width: 100vw;
  height: 100%;
  height: 70vh;
}
.shape {
  content:url(http://i1126.photobucket.com/albums/l611/ldocherty1/IMG_0730_zpsiz4dqc47.jpg);
  border-radius: 25px;
  background:grey;
  color:white;
  padding:3px;
  margin:200px auto 0 auto;
  width:200px;
  height:200px;
  position: absolute;
}
.shape2 {
  background: linear-gradient(15deg, #4D5061, #4D5061);
  border-radius: 85px;
  color:white;
  opacity: 0.9;
  padding:0px;
  margin:410px auto 0 auto;
  width:250px;
  height:40px;
  left:200;
  position: absolute;
}

6 个答案:

答案 0 :(得分：0)

使用.hero，添加text-align: center;作为属性。

像这样：

.hero{
    background-image: url("https://static.pexels.com/photos/48727/pexels-photo-48727.jpeg");
    background-attachment: fixed;
    position:relative;
    width: 100vw;
    height: 70vh;
    text-align: center;
}

从每个元素中移除position: absolute：）

答案 1 :(得分：0)

从hero，shape和shape2类中删除position元素。然后添加

position:relative

到section1类。然后减少shape2类的上边距。所有那些东西都在底部，第2节和箭头接触的东西似乎也没关系。它还需要一些修补

答案 2 :(得分：0)

将.shape的边距更改为

margin:200px auto 0 550px;

然后将.shape2的边距更改为

margin:410px auto 0 525px;

它会解决问题但不是那么敏感

答案 3 :(得分：0)

我会将.shape, .shape2包裹在一个新元素中，绝对将新元素放置在水平/垂直中心，然后将2个形状元素置于该元素中心。 

.shapes {
  left: 50%;
  top: 50%;
  transform: translate(-50%,-50%);
  position: absolute;
}
.shape, .shape2 {
  margin-left: auto;
  margin-right: auto;
}

答案 5 :(得分：0)

一种将绝对定位元素居中的技术是增加左边：50％和左边距：负面50％。

例如你的形状：

.shape {      content:url(http://i1126.photobucket.com/albums/l611/ldocherty1/IMG_0730_zpsiz4dqc47.jpg);
  border-radius: 25px;
  background:grey;
  color:white;
  padding:3px;
  margin:200px auto 0 auto;
  width:200px;
  height:200px;
  position: absolute;
  left: 50%;
  margin-left: -100px;
}

宽度是200px所以我们添加margin-left：-100px和left：50％;
