How to completely remove CSS style and not replace it?

Question

I have a style defined as follows:

td,th{padding:0}

Now I want to completely remove this style dynamically and not override it with some value, because I need the value inline/defaultset by the browser. Anyone who has any ideas on how to do this, feel free to answer.

Answer 1

In CSS 3 you can use

th,td { padding: unset; }

or

th,td { padding: initial; }

Answer 2

Try to make an initial value, i.e. Set the value to fill: initial
