Inline style with 0 value doesn't add "px"

[DjebbZ]

Hello,

The docs say :

When specifying a pixel value for your inline style prop, React automatically appends the string "px" for you after your number value.

But not for 0 (the number). On purpose ?

It's a bit weird, but I guess it is on purpose.

MDN has this: The length unit is optional after the 0.

In the react code the 'px' is not added if value === 0, see here: https://github.com/facebook/react/blob/master/src/browser/ui/dom/dangerousStyleValue.js#L45-48

It's weird because the string '0'gets expanded to '0px'. More discussion is in #1357.

Thx for the answer. I think I can close, I have the answer for the "why".

Maybe updating the docs ?
