我试图水平中心一个<div>块元素在页面上,并将其设置为最小宽度。最简单的方法是什么?我想要<div>元素内联与我的页面的其余部分。我来举个例子:

page text page text page text page text
page text page text page text page text
               -------
               | div |
               -------
page text page text page text page text
page text page text page text page text

当前回答

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>

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"
        });
    });
});

我使用div和span标签以及css属性,如块,跨浏览器内联块和文本对齐中心,见我的简单示例

<!DOCTYPE html>
<html>
    <head>
       <title>Page Title</title>
       <style>
           .block{display:block;}
           .text-center{text-align:center;}
           .border-dashed-black{border:1px dashed black;}
           .inline-block{
                 display: -moz-inline-stack;
                 display: inline-block;
                 zoom: 1;
                 *display: inline;
            }
           .border-solid-black{border:1px solid black;}
           .text-left{text-align:left;}
        </style>
    </head>
    <body>
          <div class="block text-center border-dashed-black">
              <span class="block text-center">
                  <span class="block"> 
        <!-- The Div we want to center set any width as long as it is not more than the container-->
                      <div class="inline-block text-left border-solid-black" style="width:450px !important;">
                             jjjjjk
                      </div> 
                  </span>
              </span>
          </div>
      </body>
   </html>

对这个问题最好的回答是使用margin-auto,但要使用它,你必须知道你的div的宽度在px或%。

CSS代码:

div{
    width:30%;
    margin-left:auto;
    margin-right:auto;
}

在你的html文件中,你写:

<div class="banner">
  Center content
</div>

你写的CSS文件:

.banner {
display: block;
margin: auto;
width: 100px;
height: 50px;
}

对我有用。

margin: 0 auto;

正如ck所说,不是所有浏览器都支持min-width
