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

将这个类添加到您的css文件中，它将完美地工作 步骤:
1)先创造它
<div class="center-role-form">
<!--your div (contrent) place here-->
</div>
2)添加到你的CSS
.center-role-form {
width: fit-content;
text-align: center;
margin: 1em auto;
display: table;
}

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.

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;
}
.center {
margin-left: auto;
margin-right: auto;
}
最小宽度不是全局支持的，但是可以使用
.divclass {
min-width: 200px;
}
然后可以将div设置为
<div class="center divclass">stuff in here</div>
