CSS3 Smiley

I made a smiley using only CSS. Here's the code:

smiley-class-name {
font: 108px 'Times New Roman', serif;
display: block;
color: #444;
-webkit-transform: rotate(90deg);
-moz-transform: rotate(90deg);
border: 10px solid #e6e6e6;
border-radius: 84px;
width: 148px;
height: 148px;
line-height: 1.2;
box-shadow: 0 0 6px #333 inset, 0 0 25px #999 inset;
}
