Do you remember the old WEBTV font tag Emboss. Well it is now possible using CSS to produce the same effect.
.emboss {

  color:  #000000 ;
  text-shadow: -1px 1px 0  #666666;
  font-size: 18px;
Just use the above code between the style tags and wrap the Span tags around the text you wish to emboss like so <span class=emboss>some text</span>. One word of caution: The colors used must compliment one and another to produce the desired effect.
