Opera 8 bug - please confirm

See <http://santek.no-ip.org/~st/tests/CSS/Opera/align.php>.

Would appreciate confirmation that this is a bug in Opera, not my
mistake.

If you make your code standards compliant (get rid of vspace, hspace,
put a div between the <body> element and the images, add the type
attribute to the <style> element and get rid of the align attribute on
the first image), Opera doesn't show the image twice.
The CSS equivalent of align="right", is float:right.
And yes, if you add style="float:ri ght;" to that first image, you get
to see it twice again. I find that logical though, as a floated image
can't at the same time be positioned (fixed, relative or absolute).

Trying this code in Opera, Firefox and IE, shows 3 different results.

This is a ridiculous hodgepodge of invalid presentational HTML under a
Strict doctype.

Under CSS 2.x there are 3 mutually exclusive positioning schemes
http://www.w3.org/TR/CSS21/visuren.h...tioning-scheme
Under the current rules attempting to float *and* absolutely position an
element is daft, browser behaviour in such a case is undefined.

Ah! Of course. *That* was my mistake. I mixed up float with position. I
just need to set float to none to then be able to fixed position the
image. Thanks!

Right.

Ah, yes. You're right. Sorry about that. I'm building a site. Things
behaved as they should in iCab, Opera, Mozilla and Safari. But Explorer
(both Win and Mac actually) screwed up big time. So I changed some
things to make Explorer at least display the site in a *useable* manner,
which required giving up competely on some fixed positionionig in IE and
then using the ALIGN and V/-HSPACE attributes to a specific image. I
then forgot to change the doctype declaration to Transitional and mixed
up float and fixed positioning. For the site I use external CSS of
course - when setting up examples like this I find it more comfortable
to use inline CSS, but I simply forgot the TYPE attribute to STYLE.

So, sorry about the mess. Blame Microsoft ;(

Corrected code at
<http://santek.no-ip.org/~st/tests/CSS/Opera/align3.php>. And
<http://santek.no-ip.org/~st/tests/CSS/Opera/align2.php> to show what i
was after.

Opera indeed behaves as it should. iCab Mozilla and Safari apparently
were trying to be too helpful...

In-document CSS is preferred for posting examples here, it saves us from
having to open and look at 2 or more files.

You don't need the presentational hodgepodge or a transitional doctype:
http://homepage.ntlworld.com/spartanicus/sander.htm

Note that I've also changed the positioning of the image since your
original positioning relative to the right viewport edge didn't scale
properly when the viewport width was narrowed.

Again: browser behaviour for your original code is undefined as per the
spec, thus the browsers are neither wrong nor right.

Ah, right. Good to know.

(Doesn't 'work' for the actual site though, where this structure is
itself within a float. Looks like I narrowed it down too much in my
example. I'll see if I can change the approach on the site. Would be
nice to not have to use presentational mark-up.)
Thanks for your help!

Shouldn't be a problem, specify "position:relat ive" on the float to make
it the containing block.
