我知道这个问题很老了，但我正在尝试。非常类似于bobince的答案，但有工作代码示例。

使每个产品都成为一个内联块。将容器的内容居中。完成了。

http://jsfiddle.net/rgbk/6Z2Re/

<style>
.products{
    text-align:center;
}

.product{
    display:inline-block;
    text-align:left;

    background-image: url('http://www.color.co.uk/wp-content/uploads/2013/11/New_Product.jpg');
    background-size:25px;
    padding-left:25px;
    background-position:0 50%;
    background-repeat:no-repeat;
}

.price {
    margin:        6px 2px;
    width:         137px;
    color:         #666;
    font-size:     14pt;
    font-style:    normal;
    border:        1px solid #CCC;
    background-color:   #EFEFEF;
}
</style>


<div class="products">
    <div class="product">
        <div class="price">R$ 0,01</div>
    </div>
    <div class="product">
        <div class="price">R$ 0,01</div>
    </div>
    <div class="product">
        <div class="price">R$ 0,01</div>
    </div>
    <div class="product">
        <div class="price">R$ 0,01</div>
    </div>
    <div class="product">
        <div class="price">R$ 0,01</div>
    </div>
    <div class="product">
        <div class="price">R$ 0,01</div>
    </div>
</div>

请参见:CSS中具有动态宽度的内联块居中

2015年2月27日更新:我最初的答案不断被投票，但现在我通常使用@bobince的方法。

.child { /* This is the item to center... */
  display: inline-block;
}
.parent { /* ...and this is its parent container. */
  text-align: center;
}

出于历史目的，我原来的帖子是:

您可能想尝试这种方法。

<div class="product_container">
    <div class="outer-center">
        <div class="product inner-center">
        </div>
    </div>
    <div class="clear"/>
</div>

下面是匹配的样式:

.outer-center {
    float: right;
    right: 50%;
    position: relative;
}
.inner-center {
    float: right;
    right: -50%;
    position: relative;
}
.clear {
    clear: both;
}

JSFiddle

The idea here is that you contain the content you want to center in two divs, an outer one and an inner one. You float both divs so that their widths automatically shrink to fit your content. Next, you relatively position the outer div with it's right edge in the center of the container. Lastly, you relatively position the inner div the opposite direction by half of its own width (actually the outer div's width, but they are the same). Ultimately that centers the content in whatever container it's in.

如果你依赖于你的“product”内容来调整“product_container”的高度，你可能需要在结尾使用空的div。

<style type="text/css">
.container_box{
    text-align:center
}
.content{
    padding:10px;
    background:#ff0000;
    color:#ffffff;

｝

使用span代替内部div

<div class="container_box">
   <span class="content">Hello</span>
</div>

大多数浏览器支持display: table;CSS规则。这是一个在容器中居中div的好技巧，无需添加额外的HTML，也无需对容器应用约束样式(如text-align: center;这将在容器中居中所有其他内联内容)，同时保持包含div的动态宽度:

HTML:

<div class="container">
  <div class="centered">This content is centered</div>
</div>

CSS:

.centered { display: table; margin: 0 auto; }

.container { 背景颜色:绿色; ｝ .centered { 显示:表; 保证金:0自动; 背景颜色:红色; ｝ < div class = "容器" > <div class="居中">内容居中</div> < / div >

更新(2015-03-09):

现在正确的方法实际上是使用flexbox规则。浏览器支持有点受限(CSS表支持vs . flexbox支持)，但这种方法也允许许多其他事情，并且是针对这种类型行为的专用CSS规则:

HTML:

<div class="container">
  <div class="centered">This content is centered</div>
</div>

CSS:

.container {
  display: flex;
  flex-direction: column; /* put this if you want to stack elements vertically */
}
.centered { margin: 0 auto; }

.container { 显示:flex; flex-direction:列;/*如果你想垂直堆叠元素*/ 背景颜色:绿色; ｝ .centered { 保证金:0自动; 背景颜色:红色; ｝ < div class = "容器" > <div class="居中">内容居中</div> < / div >

将这个CSS添加到product_container类中

    margin: 0px auto;
    padding: 0px;
    border:0;
    width: 700px;

<div class="product_container">
<div class="outer-center">
<div class="product inner-center">
    </div>
</div>
<div class="clear"></div>
</div>

.outer-center
{
float: right;
right: 50%;
position: relative;
}
.inner-center 
{
float: right;
right: -50%;
position: relative;
}
.clear 
{
clear: both;
}

.product_container
{
overflow:hidden;
}

如果你不提供"overflow:hidden"为"。Product_container”，“outer-center”div将与它右边的其他附近内容重叠。任何链接或按钮的右边“外中心”不会工作。尝试“outer-center”的背景色来理解“overflow:hidden”的需求
