Hi, Here is 2 similar documents, difference only in doctype declaration. http://firejuice.com/tests/div-height-tr.html http://firejuice.com/tests/div-height-x.html Seems that mozilla doesn't expand relative positioned div with height 100% in standards rendering mode, in quirks mode - everything is ok. Is there any way to make relative positioned div expand and keep doctype declaration?
