That's interesting. The thing I like about the equals sign on the left  
is that it points to the thing it is being assigned to. So for  
instance, if you ignored the CSS notation (and had the equal sign only  
on the left), you would have something like this:

  h1=myHeaderStyle
  background-color=myBackgroundColor

...which makes sense to me because you are assigning myHeaderStyle to  
the h1, and myBackgroundColor to the background-color. As a Web  
author, I am familiar with such assignments within JavaScript (and  
VBScript).

I do not understand the argument others have made that a dollar sign  
would be more natural. To me it is just another abstract symbol  
without anything to make it more understandable as a variable  
identifier. Is it because in some programming languages it is used to  
denote string-type variables?
