I have a global css definition like this

td {
     background: none repeat scroll 0 0 transparent;
}


Now I dont want to inherit these properties only inside a div tag with id="separate"
<style type="text/css">
      #separate td {inherit:none; background:''}
</style>
<div id="separate">
    ...........
    .....<td >......
    .....<td background='image.gif'>.....
    ...........
    ...........
    .....<td>.....
    ...........
</div>



As you know
inherit:none;
and
background:''   (emptyfying)
Does not exists.

How to do this ?

sorry, i cant because some td will have background & some will not.


Also If I use something like this
#separate td
{
   background:white;
}


in runtime then It automatically becomes
#separate td
{
   background:white repeat scroll 0 0 transparent;
}
instead of
   background: none repeat scroll 0 0 transparent;
from global declaration.




Basically I need to DISABLE inheritance INSTEAD of OVERRIDING with new syle.

this is not inheritance,
inheritance is from parent element to child element, and background properties are not inherited anyways

Give
#separate
{
    background: none !important;
}

If I use this
#separate td
{
   background:none;
}

then browser reads it as (copied from firebug)
#separate td
{
   background:none repeat scroll 0 0 transparent;
}


as you can see the Global declaration is same as this
td
{
   background:none repeat scroll 0 0 transparent;
}

this means new property inside #separate td is overridden & others are automatically inherited.

'td' and 'tables' don't inherit much of anything anyway.  It's an oddity that all the browsers exhibit in tests that I've done.  I think it comes from some historical context and is against the W3 standard but they do it anyway.

There is no 'generic' way, you have to add the details you want to the individual elements.  Remember that the last declaration for a particular style item and element is the one that takes effect.  If you use a CSS reset, it needs to be the very first thing in your CSS code.  Then come the general categories and then the specific details.  After all that come the inline styles which can override what came before.  A partial exception is that table elements need to be specifically styled because they don't inherit much.
