如何在页面中间居中放置3个div [英] How to center 3 divs in the middle of the page
本文介绍了如何在页面中间居中放置3个div的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我想将3个div居中到页面中间，我让每个div都向左浮动，以便它们并排，但是我希望它们在页面的中央。
Hi I want to center 3 divs to the middle of the page, I have each of them floating left so that they are side by side however I want these to be central to the page.
我将它们放在宽度为 100％的包装纸中，并尝试使用 margin：0px auto 以使其居中，但这不起作用，但是 width：100％或 width：auto ，但是，如果我指定宽度，这似乎居中，但是我不想为包装器指定宽度，我希望它是页面的大小。
I have them in wrappers with a width of 100% and have tried to use margin:0px auto in order to center this this doesn't work but width:100% or width:auto, however if I specify a width this seems to center however I don't want to specify a width to my wrapper I want it to be the size of the page.
我不确定自己做错了什么。因此，任何输入和一双新鲜的眼睛都是很棒的！
I'm not entirely sure in regards to what I've done wrong. So any input and a fresh pair of eyes would be fantastic!

推荐答案
更改 .topWrapper div设置 text-align：center 规则，然后删除 float：left 从这三个div（.left，.center和.right）中提取，并替换为 display：inline-block 。
Change the .topWrapper div to have a text-align:center rule, then remove the float:left from those three divs (.left, .center, and .right) and replace them with display:inline-block.
.topWrapper {
width:100%;
text-align:center;
}
.left {
width:200px;
height:200px;
background-color:red;
display:inline-block;
margin-right:20px;
}
.center {
width:200px;
height:200px;
display:inline-block;
background-color:blue;
margin-right:20px;
}
.right {
width:200px;
height:200px;
background-color:black;
display:inline-block;
margin-right:20px;
}
