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

九年过去了，我想是时候推出一个新版本了。以下是我最喜欢的两个(现在是一个)。

将margin设置为auto。你要知道方向序列是边距:*上* *右* *下* *左*;或边距:*上下*左右*
aside{ display: block; width: 50px; height: 100px; background-color: green; float: left; } article{ height: 100px; margin: 0 0 0 50px; /* 50px aside width */ background-color: grey; } div{ margin: 0 auto; display:block; width: 60px; height: 60px; background-color: blue; color: white; } <!DOCTYPE html> <html> <head> </head> <body> <aside> </aside> <article> <div>The div</div> </article> </body> </html>
中心:废弃的，不要用这个!
使用<center></center>标签环绕<div></div>。
例子:
aside{ display:block; background-color:green; width: 50px; height: 100px; float: left; } center{ display:block; background-color:grey; height: 100px; margin-left: 50px; /* Width of the aside */ } div{ display:block; width: 60px; height: 60px; background-color:blue; color: white; } <!DOCTYPE html> <html> <head> </head> <body> <aside> </aside> <article> <center> <div>The div</div> </center> </article> </body> </html>

.center { 高度:20 px; 背景颜色:蓝色; ｝ .center > div { 保证金:汽车; 背景颜色:绿色; 宽度:200 px; ｝ < div class = "中心" > < / div > < div >你文本 < / div >

你可以使用位置:相对;然后设置左边和上面的值:
.cenverDiv{
position:relative;
left:30%;
top:0px;
}
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"
});
});
});
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 >
