125303 - "font-size: 20 px" doesn't work (whitespace before unit)

Status: VERIFIED INVALID

(Core :: CSS Parsing and Computation, defect)

Description

[rbs]

Did a quick search in bugzilla and the CSS spec, but couldn't figure out a 
definitive answer. Currently Mozilla doesn't support numeric values in which 
whitespace preceds the unit. Is it the expected/recommended behavior? Please 
mark the bug invalid if so.

Invalid.  Not many web pages depend on this (and I think IE for Windows may be
the only browser that accepts it) and it's a good bit more complicated to parse,
especially with shorthands that can take variable numbers of values and perhaps
keywords as well, and also with properties that can take unitless numbers.

It is invalid per CSS, look at the grammar appendix.
