Hello.
Flamingo is still not HTML5 valid, so I am working on it.
We actually use some <meta> tags that are become invalid in HTML5.
= X-UA-Compatible =
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
It forces the Compatibility mode for IE browsers to use the latest
rendering mode.
We can replace it by adding the X-UA-Compatible in the HTTP headers, but I
actually propose to surround this tag like this:
<!--[if IE]>
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<![endif]-->
The code is valid (because inside a comment so the validator does not parse
it) and it is still usable with IE.
= imagetoolbar =
<meta http-equiv="imagetoolbar" content="no"/>
it disables the toolbar that comes up when you mouse over an image in MSIE.
Same, I propose to add a conditional comment:
<!--[if IE]>
<meta http-equiv="imagetoolbar" content="no"/>
<![endif]-->
= Content-Script-Type =
<meta http-equiv="Content-Script-Type" content="text/javascript"
/>
It defines the default scripting language that is used for intrinsic events
(e.g. onmouseover attributes).
This tag has been deprecated, and there is nothing to replace it. I don't
think this tag is very useful because most of the browsers assume that an
intrinsic event will be handled by javascript. Actually I did not know this
meta tag before today and my inline javascript did always work!
So I propose to just remove it.
= Distribution =
<meta name="distribution" content="GLOBAL" /> (from
XWiki.XWikiPreferences)
It actually defines either the website should be considered as public or
local (see See http://www.metatags.info/meta_name_distribution).
I propose to remove it.
= reply-to =
<meta http-equiv="reply-to" content="" /> (from
XWiki.XWikiPreferences)
To be useful, the content should not be empty, so the administrator should
set it. Moreover, it is very not well-known, and it could be a problem
since the spam bots can read it.
I propose to remove it. If the administrator wants it, she can put it in
the preferences, with the proper value filled.
= language =
<meta name="language" content="en" /> (from
XWiki.XWikiPreferences)
It is actually redundant with <html lang="en">.
I propose to remove it.
What do you think?
Thanks,
