Multiple problems w/ <a name
* in itself deprecated
* my approach of self-closing <a is illegal too
replaced w/ spans where necessary.
Further notes:
'topp' was never used; '#top' is taken too, so I went with first-frame (stil unused, 'maybe later')
The fixes in this and preceding commits were inspired by running "Nu Html Checker"
docker run -it --rm -p 8888:8888 ghcr.io/validator/validator:latest
files were simply saved in Firefox and then uploaded; make sure to ignore the warning which is caused by Firefox:
> A document must not include both a meta element with an http-equiv attribute whose value is content-type, and a meta element with a charset attribute.
I limited checking to the issue-list and various event-detail pages.
