Question

如何将div水平和垂直居中并调整高度以适应内容？

这是我的HTML代码：

 <div class="sprite">
  </div>

 <div class="content">
     <span>close</span>
     <div class="centered">

         lorem lipsum.....

     </div>

 </div>

和css：

.sprite{
    position: fixed;
    left: 0px;
    top: 0px;
    z-index: 20;
    width: 100%;
    height: 100%;
    background-color: gray;
    opacity: 0.6;
}

.content{
     border:1px solid red; 
     z-index:21; 
     position: absolute; 
     margin:auto; 
     padding:10px;
     left: 0px;
     top: 0px; 
     bottom:0px; 
     right:0px;
     height:30%; 
     width:30%;  
     text-align:center; 
}
.content span{
     position:absolute; 
     top:0px; 
     right:0px;}

.centered{
     height:100%; 
/* Internet Explorer 10 */
     display:-ms-flexbox;
     -ms-flex-pack:center;
     -ms-flex-align:center;

/* Firefox */
    display:-moz-box;
    -moz-box-pack:center;
    -moz-box-align:center;

/* Safari, Opera, and Chrome */
    display:-webkit-box;
    -webkit-box-pack:center;
    -webkit-box-align:center;

/* W3C */
   display:box;
   box-pack:center;
   box-align:center;
}

这就是我想要的：

Answer 1

编辑.content类以拥有以下css并删除绝对位置

height:auto;
overflow:visible;

Answer 2

在.content课程中，删除

position: absolute;

和添加

margin-top:24%;

在取内容高度时将其对齐在垂直中间。

absolute定位属于相当困难的风格！

在这里你去交配

CSS修改：

  .sprite{
    position: fixed;
    left: 0px;
    top: 0px;
    z-index: 20;
     width: 100%;
    /* height: 100%; */
    background-color: gray;
    opacity: 0.6;
    border:1px solid #FFF;
    text-align:center;
}

.content{
     border:1px solid red; 
     position:relative;
     z-index: 21; /* change this to less than 20 to overlay under sprite on scroll*/
     margin:auto;
     padding:10px;
     width:30%;  
     margin-top:24%;
     text-align:center; 
}

.content span{position:absolute;right:0;top:0;text-align:right; border:1px solid #F00000}

诀窍是在absolute <span>类中对齐relative content ....

Answer 5

你正在努力做到这一点，只需在班级内容中将职位改为亲戚，见下文;

 .content{
 border:1px solid red; 
 z-index:21; 
 position: absolute; 
 margin:auto; 
 padding:10px;
 left: 0px;
 top: 0px; 
 bottom:0px; 
 right:0px;
 height:30%; 
 width:30%;  
 text-align:center; 
 }

Div高度不适合内容
