In an effort to try and stay current, I have migrated this website from Bootstrap 4.6 to Bootstrap 5.3. The migration documentation is shockingly long and detailed, and I'm sure there are things that slipped through the cracks here and there. It doesn't help that version 5 expects radically different markup in some cases from its predecessor.
I am also now using a new lightbox plugin for my image gallery posts, but I find that the new plugin leaves a lot to be desired. Given how simple its code is, I'll likely roll my own version in the future to improve upon the look and feel.
If you find issues, be sure to let me know. I no longer bother using a sandbox site to test this stuff out (who needs testing?!?), so things are bound to shift around some over the coming days.
