Hi there,
I notice the site Theatre Studies: European Theatre
(http://www.theatrestudies.llc.ed.ac.uk/) has been placed in the problem
section of http://microformats.org/wiki/hcalendar-examples-in-wild due to
the use of inline style (style="display:none") used within an img tag.
Here is the code in question:
<span class="vcard">
<img style="display:none"
src="http://www.theatrestudies.llc.ed.ac.uk/images/staff/scolvin.jpg";
alt="Sarah Colvin" class="photo" />
<span class="honorific-prefix">Professor </span>
<span style="font-weight:bold" class="fn">Sarah Colvin</span><br />
Email: <a href="mailto:[EMAIL PROTECTED]"
class="email">[EMAIL PROTECTED]</a>
</span>
I am not sure why this has been done as:
A) the img is part a hCard and not an hCalender, although both exist on the
page
B) using a correctly formatted css inline markup to hide the img from the
browser renderers cannot, surely, conflict with microformat semantic
markup. Having read the brainstorming hCard FAQ I initially used <span
style="display:none"></span> around the img tag - however I see no reason in
this case to add the extra markup around the img tag. ( The is the future
'Proposed
Additions'(http://microformats.org/wiki/hcard-parsing#Use_of_CSS_compute
d_styles_instead_of_HTML_default_styles) but this is for text formating, as
far as I can see, so it wouldn't interfere with an img file getting parsed
correctly.)
Using the Tails (0.3.6) Firefox add-on correctly parses the microformat
content on this page including the image.
Can anyone explain why the inline css style (display:none) cannot co-exist
(ignoring the benefits of using external style sheets rather than inline
css) with the microformat semantic markup. I'm probably missing something
obvious here, so thanks for any advice.
Cheers

Hi Euan,
I've looked at this twice now and I can't see an obvious reason for
the hCard to be incorrect. There is on-going debate on whether hiding
information is a good or bad idea, but the actual mark-up you've used
is correct and I've no trouble at all parsing your card in Tails,
Operator, etc.
If you look at hcard-issues [1] you'll find discussions on negative
impacts of hiding entire cards, but not specifically hiding a single
part of it. Afterall, if the photo of your card was skipped, it would
still be a valid hCard without it.
You should carefully consider whether you want to hide the photo of
your card, and whether you want to do this inline especially.
Anyone else like to chime in? I'm not totally sure here.
