Kinda font-related, it's throwing me off how every V in the Latin texts show as U. I don't like how they modernized the spellings in school, but if you're not doing that, aren't they all V?
Also most of the word popups use different spellings, like "iam" becomes "jam".
Using either spaces or miniscule letters, is anachronistic for both classical Latin and Greek. They only had a single case in antiquity and didn't usually mark word boundaries.
Sort of. Romans didn't handwrite like that. See https://en.wikipedia.org/wiki/Roman_cursive . Note that the "u" character in both ancient and late ancient Roman cursive is more like the modern "u".
A web interface to classical texts is going to be anachronistic.
If its purpose is pedagogical, it should include macrons, spaces, punctuation, case -- the works. Making every word clickable but leaving the reader to guess at vowel length seems like leaving the job half done.
