Over-qualified CSS selectorsEdit
My apologies that this message is just available in English.
Over-qualified CSS selectors of portals in Wikimedia skins have been changed.
div#p-variants are now all removed of the
div qualifier, as in for example it is
#p-personal, #p-navigation …. This is so the skins can use HTML5 elements. Your gadgets or user styles seem to use them and you will have to update them. You can read more in phab:T252467. Johan (WMF) through MediaWiki message delivery (talk) 12:27, 8 June 2020 (UTC)
Your sandbox edit came up in our logs: https://meta.wikimedia.org/?diff=20735027. The reason the close span tag is being removed is because the bold tag starts before it and finishes inside it, which forces the span to close. You should either move the close span tag up to inside the bold end, or move the open span tag to before the bold starts. Hope this helps. ESanders (WMF) (talk) 13:00, 2 December 2020 (UTC)
