我在子div中用float left后，div居然居中了，不用float它到是自己在左边，百思不得其姐啊，有谁碰到过这个情况吗，在线等，急急急！！！

回复讨论(解决方案)

谁碰到过这个问题吗，到底是哪里设置了什么会变这样

你把源代码贴出来吧

可能是受上面的浮动影响，你清楚浮动就好了

这并不奇怪，具体是什么问题你要把代码贴出来。
会出现你这种情况两个div第一个div1float:left。第二个div在没有设置flaot：left时靠左边，设置后，靠着第一个div所以看起来居中。

这是不可能的，子div 不会跑到父div 的外面去

就是一个父div中有几个子div,我全用float left让它们排成一排，但是它们居然是从父div中间开始排成一排的，margin padding都是0，原代码太长，不好贴出来，应该是别的什么div设置导致这样的

你写出来看看怎么样情况下里面的div会剧中

大神，是因为宽设了100%吗，我的宽不是100的

贴上你的代码，附上发现bug的浏览器及版本。

应该占位原因，width:100%，与float质检产生的

是的,应该占位原因，width:100%，与float质检产生的

大神，是因为宽设了100%吗，我的宽不是100的关键不是那个，是span加了这句“float:left”后，使width:100%生效。。只是打个比较，你看看是不是这种情况。像span默认是display:inline类型的，设置宽高是没效果的！加了float后才有效果的。

为什么问题和实际贴出来的代码就是不一样

span 和 div 是一个东西吗？

width：100%了还有什么剧中不剧中的 100% 不就是撑满
