I took some online web programming classes a while ago, and there are SO MANY ways that devices and browsers interpret the presented programming language(s).
I've done a few of these state/county vote fraud posts, and intend to do more [if I don't get harassed by vote fraud deniers].
I can at least make header notes for cases like yours, because I've seen that a lot of people are moving away from fry-your-eyes screen presentations.
