How important is it to leave out the last ';' inside a set of CSS rules?

Question

I\'ve had problems with Internet Explorer not applying the last property in a list of CSS properties. Is it necessary to leave out the last ; from a list of CSS

Answer 1

Additional advice: Be absolutely sure you don't accidentally end a line with double semicolons, like

.aStyle {
  background-color: #FFFFFF;;
  color: #000000;
}

This can have the extremely unhappy effect of negating every single style that comes after it on the page. It is not at all like an additional semicolon at the end of a line of Javascript, which has no effect whatsoever except to add a character to the page weight.
