i have my doctype set as:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

but this is not rendering z-indexed layers at all.

i tried <!doctype html> and it still does not work.

so my question is in order for stacked layers to work which doctype should i declare?

thank you for your help.

EDIT: i think stack layering is not a part of HTML any more, from w开发者_运维知识库eb searchs i gather. how do i go about placing an image on top of another image then? thanks!

EDIT: it is dependant on which version of doctype being used. the layering works in compability mode but not in normal mode.

What the hell are you talking about there.

For z-index to work, element must be positioned either as absolute or relative. And it has nothing to do with doctypes.
