具有绝对/固定子代的父容器上的自动高度

当父级div

height:auto

您将需要使用Javascript来实现此目的。

jQuery中的一个示例：

var biggestHeight = 0;// Loop through elements children to find & set the biggest height$(".container *").each(function(){ // If this elements height is bigger than the biggestHeight if ($(this).height() > biggestHeight ) {   // Set the biggestHeight to this Height   biggestHeight = $(this).height(); }});// Set the container height$(".container").height(biggestHeight);
