I received an informational email from Google that some of my pages were not displaying correctly on mobile devices, for example the following:
The problem as far as I can tell is the list of radicals, it was saying
部首 冂(けいがまえ・まきがまえ・えんがまえ・どうがまえ)
and this seemed to make the basic information box become too big. I tried some CSS methods like line-break, and using spaces instead of centre dots for the radical names, but unfortunately that didn't work. So what I did is to alter the main kanji pages so that only the first radical name is shown, so it now says
部首 冂(けいがまえ)
on the above page, but keep all the radical names on the radical page:
The remaining nagging concern I have is whether the first radical name is really the best one in all cases.
I also did some work on centring the initial kanji and the final line containing the date of the page update.
The deletion of old pages from the site is now semi-automated in that I have set up a job to periodically scan the site for old files and message me about them.
