I have a table and also a CSS Rule *{margin:0;padding:0;}
*{margin:0;padding:0;}
Now I want to nullify the effect of \"margin:0<
margin:0<
I don't think it is possible: declaring * { margin: 0; padding: 0; } removes the default values, and you cannot "restore" them, unless you have some known default values (you don't know which values the browser has by default).
* { margin: 0; padding: 0; }
