anything with !important will override anything of the same CSS style and works all the way down to ie6!

here's a little snippet that is ordered from weakest to strongest!

.imALittleWeakClass {
   color: #111;
}
#imABigStrongId {
   color: #222;
}
.imALittleWeakClassMadeStronger {
   color: #333 !important;
}
#imABigStrongIdMadeEvenStronger {
   color: #444 !important;
}

as you can see id is stronger than class, but with !important, a class is stronger than an id! Nonetheless, an id with !important is GOD!

initially, ids override classes, but even a class can override an id with !important!
this allows for an expanded amount of control over your elements!
