Solution

  • The error is here:

    .btnSmall span{
    #....
    -moz-box-shadow:    inset 0 2px 2px -2px 
          rgba(255,255,255,255,.75),
          inset 0 0 0 #fff;
    }
    

    There is one of 255 too much. There are 3 occurrences of this in your code. Simply search for rgba(255,255,255,255,.75) to find them all.
