s4-die
By Anatoly Mironov
s4-die is a funny stuff. Now I realized the purpose of it. Everything that has to be hidden, Microsoft wraps in an element with class=“s4-die”. In corev4.css it is defined with display:none. Not so bad. Another approach is to create a invisible panel like Randy Drisgill has done. But with s4-die you don’t need to move your stuff around, just add the class s4-die.
