190780 - span rendering error - target anchor side effect

Status: CLOSED INVALID

(Core :: Layout, defect)

Description

Build 2003011412

The entire line containing the word "UIP" should be brown on green.
As long as I leave the <a id=... tag active, green is only shown up to the
hyperlink and "view source" claims that span ends there (which it doesn't!).
When I comment it out, the entire line is green as supposed to be?

It does validate as xhtml11 and css2!

P.S.: I have other files with where the a id= tag is also present and the error
doesn't show?!?!?

It is effect of unclosed previous <a> tag. 

<a id="contStart" />
<br />
<span class="UIP" ><strong>UIP:</strong> The sender now receives <a
href="PleaseResendMUC.msg" title="this Alert mail">this 

So first anchor maked whole space until <a href> an :taget area. Hereby <span>
block finished with <a href>.

to my knowledge "<a ... />" is equivalent to "<a ...>...</a>" and
validator.w3c.org seems to think that too - (so does MSIE).
Therefore, do you contend that w3c and MSIE are wrong or is Mozilla wrong?

[Ruslan Ismailov]

Well. If you add style="border: solid", you find, that IE think's same as
mozilla in this case.

Comment 4

[Ralf Hauser]

but even if MSIE thinks the same, contrary to Mozilla, it renders correctly (or
is w3c.org validation wrong?)

Comment 5

[Ruslan Ismailov]

Do I say this bug is invalid? I don't know yet. I say, that it seems to be
effect of :target for <a />. 

BTW. w3c validation means only that code is correct. But validation have nothing
with render.

In XML.  Not in HTML.  You're sending the page as text/html, which means "render
as HTML".  The page is XHTML and XHTML may only be send as text/html if it
complies with Appendix C of the XHTML 1.0 specification.  Which this page does not.

IE's DOM and layout model are unrelated, which is why it works in IE.

The validator just says this is a valid XHTML document (which it is).  But we
can't parse it as XML for the reasons listed at http://www.hixie.ch/advocacy/xhtml
