我添加了2个按钮来显示和隐藏加载文本。我希望“加载文本”本身始终位于“kl”div的中间，即使在滚动/调整窗口大小时也是如此。

即使top / left = 50％且position = absolute，文本也不居中（主要是调整大小）。我需要做些什么来使其正确居中。

Answer 1

检查:http://jsfiddle.net/8b6zk90c 只是我添加了位置：相对于外部和内部div到位置：固定

Answer 2

您好您可以添加两个属性来实现kl DIV中间的文本

text-align: center;
line-height: 700px;

它会做魔术

Html文本不居中
