Is there a shortcut for setting !important on every property in a CSS file?

Question

I have a large CSS file for which I would like to add !important to every CSS property. Is there one-line shortcut to make a whole .css file !important

Answer 1

No. Using !important should only be in specific no-other-way cases. It is not intended to be applied to a whole stylesheet document.

If you are thinking about overwriting so many rules why not just not include the rules you want to overwrite?
