<style> 
.div1,.div2
{
	column-count:3;
	-moz-column-count:3; /* Firefox */

<h2>英国维斯米斯特教堂碑文</h2>
当我年轻的时候，我梦想改变这个世界；当我成熟以后，我发现我不能够改变这个世界，我将目光缩短了些，决定只改变我的国家；当我进入暮年以后，我发现我不能够改变我们的国家，我的最后愿望仅仅是改变一下我的家庭，但是，这也不可能。当我现在躺在床上，行将就木时，我突然意识到：如果一开始我仅仅去改变我自己，然后，我可能改变我的家庭；在家人的帮助和鼓励下，我可能为国家做一些事情；然后，谁知道呢?我甚至可能改变这个世界。
