Answer 1

Here look at how I done it; Jsfiddle

With the Code I put in, I managed to get it working on Webkit (Chrome/Safari) and Firefox. I don't know if it works with the latest version of Opera. Yes it does work under the latest version of Opera.

#wrapper {
  width: 300px; height: 300px;
  border-radius: 100px;
  overflow: hidden;
  position: absolute; /* this breaks the overflow:hidden in Chrome/Opera */
}

#box {
  width: 300px; height: 300px;
  background-color: #cde;
  border-radius: 100px;
  -webkit-border-radius: 100px;
  -moz-border-radius: 100px;
  -o-border-radius: 100px;
}
