I would like a div to take all the screen height, that's why I found the following links: * http://www.webmasterworld.com/forum83/200.htm * http://www.thefutureoftheweb.com/blog/100-percent-height-interface the tricks: make the container have a specified height, for example: `body{height:100%}` seems work fine, however, I found that: once you add some doctype claim, for example: It doesn't work, at least at Firefox 3.*, it doesn't work. Any suggestions?
