最近在学关系型数据库相关，MySQL 和 Postgre,捎带着学了 PHP，为了练手这几天就忙着自己搭博客，项目部署在某云上，该云算是良心，给的空间自己搭博客用足够了。本来想着每日一bo的,所以有的时候实在来不及就只能隔天更新了。以后尽量发点东西出来，等博客搭完写一写 SQL 数据库基础相关的分享，给跟我一样的小白道友们做下参考，大神请直接无视~

说到居中，很多人第一反应应该是水平居中，说到水平居中，肯定道友们有一万种方法做到，CSS3 的FlexBox更是强大到没朋友。但是良辰今天想聊的是 CSS 垂直居中的方法，下面是萌萌的分割线。神马？你敢说不萌？

方式一：table 布局方法

直接上?：

<!DOCTYPE html><br /><html lang="en"><br /><head><br />    <meta charset="UTF-8"><br />    <title>Title</title><br /></head><br /><body><br /><style><br />    .container{<br />        width: 200px;<br />        height: 200px;<br />        font-weight:bold;">deepskyblue;<br />        display: table;<br />    }<br />    .cell{<br />        display: table-cell;<br />        vertical-align: middle;<br />        font-weight:bold;">lawngreen;<br />    }<br />    .content{<br />        font-weight:bold;">yellow;<br />    }<br /></style><br />    <div class="container"><br />        <div class="cell"><br />            <div class="content"><br />                Content<br />            </div><br />        </div><br />    </div><br /></body><br /></html>

效果：

分析

优点：content 高度可以动态改变，无须担心父级容器高度不够被截断；

缺点：IE8 还没搞定。　　

方式二：布局对象固定高度

<!DOCTYPE html><br /><html lang="en"><br /><head><br />    <meta charset="UTF-8"><br />    <title>vertical-center</title><br /></head><br /><body><br />    <style><br />        .container{<br />            width: 200px;<br />            height: 200px;<br />            background-color: #003366;<br />            position: relative;<br />            text-align: center;<br />            display: table;<br />        }<br />        .content{<br />            width:100px;<br />            height: 100px;<br />            background-color: yellow;<br />            position: absolute;<br />            top:50%;<br />            margin-top: -50px;<br />　　　　     left:50%;<br />　　        margin-left:-50px;  <br />        }<br />        .point{<br />            width:50px;<br />            height: 50px;<br />            position: absolute;<br />            top: 50%;<br />            margin-top: -25px;<br />            left:50%;<br />            margin-left:-50px;<br />            background-color: green;<br />        }

    </style><br /><br />    <div class="container"><br />        <div class="content"><br />            <div class="point"><br />                point goes here.<br />            </div><br />        </div><br />    </div><br /></body><br /></html>

就这样，我们实现了垂直和水平的居中

上面提到的方法，都有局限性，下面介绍一种通用的方法，不过是 CSS3实现的，但是通用。

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"><html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en"><head> <meta http-equiv="Content-Type" content="text/html;charset=UTF-8"> <title>haorooms不固定高度div写法</title> <style>.center { position: fixed; top: 50%; left: 50%; background-color: #000; width:50%; height: 50%;-webkit-transform: translateX(-50%) translateY(-50%);} </style></head><body> <div class="center"></div></body></html>

看吧，我们只是吧 margin 变成translate，其他浏览器的写法如下：

-webkit-transform: translateX(-50%) translateY(-50%);-moz-transform: translateX(-50%) translateY(-50%);-ms-transform: translateX(-50%) translateY(-50%);transform: translateX(-50%) translateY(-50%);

justify-content:center;//子元素水平居中align-items:center;//子元素垂直居中display:-webkit-flex;

就先写这么多吧，先吃饭去啦~
