Poor pseudo-classes and emulated attribute selectors in IE

I'm trying to imitate some pseudo-classes and attribute selectors in Internet Explorer 6 and 7, for example :focus

, :hover

or [type=text]

. So far, I've managed to add the class name for the affected items:

$("input, textarea, select")
.hover(function(){
    $(this).addClass("hover");
}, function(){
    $(this).removeClass("hover");
})
.focus(function(){
    $(this).addClass("focus");
})
.blur(function(){
    $(this).removeClass("focus");
});

$("input[type=text]").each(function(){
    $(this).addClass("text");
});

      

        
        
        
      

    

However, I still have to duplicate the selector in my stylesheets:

textarea:focus, textarea.focus{
}

      

        
        
        
      

    

And to make matters worse, IE6 seems to ignore all selectors when it finds an attribute:

input[type=text], input.text{
    /* IE6 ignores this */
}

      

        
        
        
      

    

And of course IE6 ignores the multi-class selector:

input.text.focus{
    /* IE6 ignores this */
}

      

        
        
        
      

    

So, I will most likely end up in this mess:

input[type=text]{
    /* Rules here */
}
input.text{
    /* Same rules again */
}
input[type=text]:focus{
}
input.text_and_focus{
}
input.text_and_hover{
}
input.text_and_focus_and_hover{
}

      

        
        
        
      

    

My question is, is there a way to read the rules or computed style defined for a CSS selector and apply it to specific elements, so I only need to maintain one set of standard CSS?
