你可以在CSS上使用margin: 0 auto而不是margin-left: auto;margin-right:汽车;

问题的标题和内容实际上是不同的，所以我将发布两个解决方案，使用Flexbox。

我猜在IE8和IE9完全被摧毁之前，Flexbox将取代/添加到当前的标准解决方案中;)

检查当前flexbox的浏览器兼容性表

单一的元素

.container { 显示:flex; justify-content:中心; ｝ < div class = "容器" > < img src = " http://placehold.it/100x100 " > < / div >

多个元素，但只以一个为中心

默认行为是flex-direction: row，将所有子项对齐在一行中。将其设置为flex-direction: column将有助于堆叠的行。

.container { display: flex; flex-direction: column; } .centered { align-self: center; } <div class="container"> <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. </p> <div class="centered"><img src="http://placehold.it/100x100"></div> <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. </p> </div>

在大多数浏览器，这将工作:

div.centre { 宽度:200 px; 显示:块; background - color: # eee; margin-left:汽车; margin-right:汽车; ｝ <div class=" center ">一些文本</div>

在IE6中，你需要添加另一个外部div:

div.layout { text-align:中心; ｝ div.centre { text-align:左; 宽度:200 px; background - color: # eee; 显示:块; margin-left:汽车; margin-right:汽车; ｝ < div class = "布局”> <div class=" center ">一些文本</div> < / div >

CSS, HTML: Div.mydiv{宽度:200px;Margin: 0 auto} < div class = " mydiv”> 我在中间 < / div >

您的图表还显示了块级元素(通常是div)，而不是内联元素。

在我的头顶，在FF2+/Safari3+/IE7+中支持min-width。可以在IE6上使用巧妙的CSS，或者简单的JS。

使用jQuery:

$(document).ready(function() {
    $(".myElement").wrap( '<span class="myElement_container_new"></span>' ); // for IE6
    $(".myElement_container_new").css({// for IE6
        "display" : "block",
        "position" : "relative",
        "margin" : "0",
        "padding" : "0",
        "border" : "none",
        "background-color" : "transparent",
        "clear" : "both",
        "text-align" : "center"
    });
    $(".myElement").css({
        "display" : "block",
        "position" : "relative",
        "max-width" : "75%", // for example
        "margin-left" : "auto",
        "margin-right" : "auto",
        "clear" : "both",
        "text-align" : "left"
    });
});

或者，如果你想用".myElement"类居中每个元素:

$(document).ready(function() {
    $(".myElement").each(function() {
        $(this).wrap( '<span class="myElement_container_new"></span>' ); // for IE6
        $(".myElement_container_new").css({// for IE6
            "display" : "block",
            "position" : "relative",
            "margin" : "0",
            "padding" : "0",
            "border" : "none",
            "background-color" : "transparent",
            "clear" : "both",
            "text-align" : "center"
        });
        $(this).css({
            "display" : "block",
            "position" : "relative",
            "max-width" : "75%",
            "margin-left" : "auto",
            "margin-right" : "auto",
            "clear" : "both",
            "text-align" : "left"
        });
    });
});

margin-left:auto和margin-right:auto的用法在某些情况下可能不起作用。这里有一个解决方案，它总是有效的。您指定一个所需的宽度，然后将左距设置为剩余宽度的一半。

    <div style="width:80%; margin-left:calc(10%);">
        your_html
    </div>
