CSS 在 div 中居中显示内容

我需要将 html 内容集中在一个 div 类 = “ partners”(顶部有两个图像的 div)中。从下面的图片中可以看到(它浮动在左边而不是 div 的中心) :

enter image description here

这是我的 html 代码:

<div id="partners">
<div class="wrap clearfix">
<h2>Partnertnerzy serwisu:</h2>
<ul>
<li><a href="http://www.dilbert.com/"><img width="56" height="16" alt="Parnter bar wika" src="/as/partners/wika.png"></a></li>
<li><a href="http://www.youtube.com><img width="65" height="15" alt="Parnter bar siemens" src="/as/partners/siemens.png"></a></li>
</ul>
<a class="linkClose" href="/firmy?clbp=1">Zamknij </a>
</div>
</div>

CSS:

#partners, #top {
position: relative;
z-index: 100;
}
#partners {
margin: 12px 0 3px;
text-align: center;
}
.clearfix:after, .row:after {
clear: both;
content: ".";
display: block;
height: 0;
visibility: hidden;
}
#partners .wrap {
width: 655px;
}
.wrap {
margin: 0 auto;
position: relative;
width: 990px;
}
#partners h2 {
color: #A6A5A5;
float: left;
font-weight: normal;
margin: 2px 15px 0 0;
}
#partners ul {
float: left;
}
ul {
list-style-position: outside;
list-style-type: none;
}

To center a div, set it's width to some value and add margin: auto.

#partners .wrap {
width: 655px;
margin: auto;
}

EDIT, you want to center the div contents, not the div itself. You need to change display property of h2, ul and li to inline, and remove the float: left.

#partners li, ul, h2 {
display: inline;
float: none;
}

Then, they will be layed out like normal text elements, and aligned according to text-align property of their container, which is what you want.

The problem is that you assigned a fixed width to your .wrap DIV. The DIV itself is centered (you can see that when you add a border to it) but the DIV is just too wide. In other words the content does not fill the whole width of the DIV.

To solve the problem you have to make sure, that the .wrap DIV is only as wide as it's content.

To achieve that you have to remove the floating in the content elements and set the display property of the block levels elements to inline:

#partners .wrap {
display: inline;
}


.wrap { margin: 0 auto; position: relative;}


#partners h2 {
color: #A6A5A5;
font-weight: normal;
margin: 2px 15px 0 0;
display: inline;
}


#partners ul {
display: inline;
}


#partners li {display: inline}


ul { list-style-position: outside; list-style-type: none; }

do like this : 

child{
position:absolute;
margin: auto;
top: 0;
bottom: 0;
left: 0;
right: 0;
}

There are many ways to center any element. I listed some

  1. Set it's width to some value and add margin: 0 auto.

.partners {
width: 80%;
margin: 0 auto;
}

  1. Split into 3 column layout

.partners {
width: 80%;
margin-left: 10%;
}

  1. Use bootstrap layout

<div class="row">
<div class="col-sm-4"></div>
<div class="col-sm-4">Your Content / Image here</div>
</div>

Try using flexbox. As an example, the following code shows the CSS for the container div inside which the contents needs to be centered aligned:

Depending on the axis of the flexbox, you will need to align or justify items, read more at MDN

.absolute-center {
display: -ms-flexbox;
display: -webkit-flex;
display: flex;


-ms-flex-align: center;
-webkit-align-items: center;
-webkit-box-align: center;


align-items: center;
justify-content: center;
}

You just need 

.parent-div { text-align: center }

You just do CSS changes for parent div

.parent-div {
text-align: center;
display: block;
}
小开

in parent div

parentDiv: {
display:flex;
height:100%;
width:100%;
justify-content:center;
align-items:center;
}
