Take the 2-minute tour ×  I'm trying this html code  <style
type="text/css"> body { background-color : green !important;
background-color : red; } Hello World !  In firefox, it's
working fine : green background. In internet explorer : it's not
working : also green background.  If I remove the doctype, it's
working fine in both. I tried different doctypes but always the
same problem.  What can I do ?  share|improve this question Not
sure if trolling, or just disbelief that IE can actually follow

HTML>. Go with the flow!. Also what version of Firefox and what
version of IE? because if it is IE6 or IE11, that kinda matters.

to be different in I
