Please see the below link in both ie8 and firefox.
orange lavalamp is ok in firefox.
but in ie8 there are some guidelines (Vertical & Horizontal guideLines Around the Low opacity gray oval... like border-right:1px solid orange; and border-bottom:1px solid orange;)
how can I remove these guidelines? because this problem is in ie , so I can not not use firebug (firefox extension to figure out the problem)!
i figured out this problem occured because of my IE8 In Windows 7 / so i updated it to IE9 and now every thing is ok /
i test it in another IE8 in windows XP and every thing was ok / i did n't figure out what was the problem about IE8 In windows 7!
