136416 - An HTML HR is not constrained to its containing DIV

Status: RESOLVED DUPLICATE of bug 84887

(Core :: Layout, defect, P2)

Description

[Stephen Moehle]

On a page with two side-by-side DIVs and one of the DIVs has an HR element, the
HR will extend across the entire page rather than being constrained to the
containing DIV.  I think this is wrong.  So evidently does the person who wrote
the Blogging software used by EFF.

I will attach a simplified testcase which looks fine in IE6 and NN4 but not in
Mozilla.

Tested with Mozillla trunk 2002-04-09-03 on Win2000.

Attachment: Test above with colours

Adding colours to the previous test file shows the HR is correctly the width of
it's parent DIV, but that the DIVs are not side by side.

[Arunan Balasubramaniam]

So the DIVs are not side by side as blue is a float and does not affect the box
of red ... so should the HR count as a line box (and act as the text does and
flow around the float) or a block box as it seems to now?

Attachment: Same test case with no DOCTYPE.

Comment 7

[Arunan Balasubramaniam]

HR is a block level element according to my HTML 4.01 sidebar so the testcase
give which has strict DOCTYPE seems to be correct behaviour.  Taking out the
doctype gives the behaviour that the reporter expects.  So I think this bug
should be closed INVALID.
