浮动的子元素溢出父div

时间：2015-08-24 14:43:25

标签： html css css3

我的浮动子div不包含在父div中，我已经尝试了很多堆栈溢出的解决方案，但是没有一个有效。我使用100％页面大小的div，然后填充，两个包含两个浮动div。两个浮动div的高度设置为100％，但是，它们的高度不是父div的100％这就是为什么他们溢出来的原因。我不想使用隐藏溢出作为解决方案。

答案 1 :(得分：0)

除非您的大小调整是边框，否则您的边距，填充和边框大小不会包含在您的高度/宽度计算中。他们是额外的！

更改为边框，以便在宽度/高度百分比内包含边框和填充。

还可以从body标签上的浏览器样式重置边距。

这是你要找的？
