26209 - Fixed Positioning: Not inline with W3C results

Status: VERIFIED DUPLICATE of bug 26584

(Core :: CSS Parsing and Computation, defect, P3)

Description

[displague]

When you cut the source on that page into a new html file and try to view it in
mozilla (sorry i am only using 12) mozilla just copysblocks of it's own memmory
space around the canvas - like randomly placed copies of partial scrollbars and
the mozilla logo from the upper right corner.

Once you add a little content to the div (as i used it for a page template) you
find that mozilla places the footer over the header.  After playing with it, i
found that if you change the position from 'auto' to a percentage or to a pixel
location it works.

The funny thing, as i see it, is that w3c says themselves if the units of
something are not specified it should be ignored - the value should be ignored.
in their example the 'px' was not specified.  This is why I believe mozilla
would not work when i simply tried to set top and bottom to 100 rather than
100px.  (I assume that in the case of a 0 value - the units are irrelevant or
ignored.)

It could be a dup of bug 26584. Reassigned to Troy.

Yup, this is a DUP of 26584.

As far as units go, the CSS2 spec says that a length identifier is required. The 
only exception is for a value of 0. That means '100' is illegal and '100px' is 
correct
