Wish: TeX approximation in HTML mode

[Krzysztof Żelechowski]

The macro @TeX{} in HTML mode generates just "TeX".  I think an approximation 
using CSS would me more appropriate.
<SPAN CLASS="TeX.logo" ><SPAN CLASS="TeX.logo.T" >T</SPAN ><SPAN 
CLASS="TeX.logo.E" >e</SPAN ><SPAN CLASS="TeX.logo.X" >X</SPAN ></SPAN >
