is there a list of default values of css properties ? (so I can make an exclusion array in js for them)

Question

All sites that list css properties such like MDN or w3schools list every CSS property on separate pages.

You can create a new element with the same tag you are examining, and not append it to the document. It will have a style object with only the defaults set, and can be compared to the element in question- but it seems silly.

The defaults are just as real as any style assignments in style sheets- the browser does not ignore them, why would you?
