J commented on WICKET-4846:
---------------------------
"Perhaps meta-tags should be placed first in head?"
I agree, as this otherwise (can) cause an bug with w3c validation (
http://validator.w3.org/check)
Try the following html (from wicket generated page) in validator:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"; xml:lang="sv" lang="sv">
<head><script type="text/javascript"

/>
<meta charset="utf-8"/>
<title>no</title>
<meta name="description" content=""/>
<body>
</body>
</html>
Gives validation error
" A charset attribute on a meta element found after the first 512 bytes.
<meta charset="utf-8"/>"
Then move the metatags to before the script generation. It will now validate!
Reason is html 5 needs the meta before 512 bytes, it has changed since html 4
(where it was more loose regarding that aspect.
Therefore the scripts and stuff should be generated after meta tags in header.
> meta viewport tag should be placed first in head

> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 6.0.0, 6.1.0, 6.1.1, 6.2.0
> Reporter: Johannes Odland
> Priority: Minor
>
> As the sequence of header contributions changed with wicket 6.0 viewport tags
> from the page are now placed after css and javascript contributed from
> subpages and components.
> The meta viewport tag must be placed before any css is loaded for media
> queries to work properly.
> Perhaps meta-tags should be placed first in head?
