本文介绍了css / html - 在父div之间传播子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
我的问题是，我有一个div（id = service-section-container），它包含3 divs（class = service-section），它们被移动到它们父div的左边。我没有找到一个有效的方法来集中儿童div使用边缘，因为使用像素将有不同的屏幕不同的结果，百分比没有做的伎俩。
My issue is that I have a div (id=service-section-container) which contains 3 divs (class=service-section) which are shifted to the left of their parent div. I haven't found an efficient way to center the group of child divs using margins as using pixels would have a different result of different screens where as percentage didn't do the trick.
这可能是一个简单的解决方案，我无法用我缺乏的经验来解决，因此为什么我真的很感激你的帮助。
It's probably a simple fix which I couldn't solve with my lack of experience, hence why I'd really appreciate your help.
示例可以在链接： http://jsfiddle.net/6tob3q1z/2/
注意：你可能需要缩小小提琴来理解我在说什么，在1000px有问题的div（服务部分）将重新定位在彼此之上
Note: You might need to zoom out on the fiddle to understand what i'm talking about as at 1000px the divs in question (service-section) will re-position to on top of each other

推荐答案
我会为这3个服务div使用wrapper， center div
i would use wrapper for those 3 service divs and set a width for it and center that div
.wrap {
width: 90%;
margin: 0 auto;
display: block;
}
.section {
width: 32.3%;
background: red;
height: 200px;
margin: 3px;
float: left
}
<div class="wrap">
<div class="section"></div>
<div class="section"></div>
<div class="section"></div>
</div>
