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.

When I\'m iterating over CSSStyleDeclaration I get

Answer 1

Here's a list of initial values I created after finding the w3 spec documents expectedly difficult to read:

var inheritedStyleInitialValues = {
    'azimuth': 'center',
    'border-collapse': 'separate',
    'border-spacing': '0',
    'caption-side': 'top',
    'color': '', 
    'cursor': 'auto',
    'direction': 'ltr',
    'elevation': '',
    'empty-cells': 'show',
    'font-family': '',
    'font-size': 'medium',
    'font-style': 'normal',
    'font-variant': 'normal',
    'font-weight': 'normal',
    'letter-spacing': 'normal',
    'line-height': 'normal',
    'list-style-image': 'none',
    'list-style-position': 'outside',
    'list-style-type': 'disc',
    'orphans': '2',
    'pitch-range': '',
    'pitch': '',
    'quotes': '',
    'richness': '',
    'speak-header': '',
    'speak-numeral': '',
    'speak-punctuation': '',
    'speak': '',
    'speak-rate': '',
    'stress': '',
    'text-align': 'left',
    'text-indent': '0',
    'text-transform': 'none',
    'visibility': 'visible',
    'voice-family': '',
    'volume': '',
    'white-space': 'normal',
    'widows': '2',
    'word-spacing': 'normal'
}

Note that these are only the styles that descendant dom nodes inherit from their ancestors (because those are the only ones I care about for what I'm working on). The ones left blank I either couldn't find defaults for or vary between browsers.

I made this a community wiki so feel free to add to this list
