--- Comment #1 from Frédéric Wang (:fredw) - OOO until January 6 <fred.wang at free.fr> ---
These are the relevant spec definitions:

getComputedStyle(): https://drafts.csswg.org/cssom/#extensions-to-the-window-interface

CSS declaration block: https://drafts.csswg.org/cssom/#css-declaration-block

CSS declaration: https://drafts.csswg.org/cssom/#css-declaration

Serialize a CSS declaration: https://drafts.csswg.org/cssom/#serialize-a-css-declaration

Serialize a CSS value: https://drafts.csswg.org/cssom/#serialize-a-css-value

Serialize a CSS component value: https://drafts.csswg.org/cssom/#serialize-a-css-component-value

<length>
    The <number> component serialized as per <number> followed by the unit in its canonical form as defined in its respective specification.
    ISSUE 12: Probably should distinguish between specified and computed / resolved values.

<number>
    A base-ten number using digits 0-9 (U+0030 to U+0039) in the shortest form possible, using "." to separate decimals (if any), rounding the value if necessary to not produce more than 6 decimals, preceded by "-" (U+002D) if it is negative.
    Note: scientific notation is not used.

<percentage>
    The <number> component serialized as per <number> followed by the literal string "%" (U+0025).
