How to regulate height of LIs?

I have a U开发者_如何学JAVAL where the LIs are boxes. I want the boxes to all be the same size, but sometimes the boxes are one line, and other times they're two. how do i add an extra empty line in the LI if the content is only one line? I'm assuming this will be some sort of javascript?

Without seeing any of your HTML markup, you could use CSS height or min-height properties. The latter will only work in the latest browsers, e.g. not IE6.

You should just give them all a certain 'height' or 'min-height' attribute instead of trying to fix a height that is automatically rendered to them.

Try posting some of your html so we can help you more though...

Maybe this could suffice?

line-height: 2em
