The interns ran into a problem I haven’t been able to diagnose. On their log-in page in Chrome for iOS, sometimes the CSS doesn’t load. Then, when you press the back button, the styles are missing on that page, too. They already had some cache-busting in place, and I couldn’t find anything wrong in the markup. On top of that, I couldn’t reproduce the problem running the server on my computer. We finally conceded that some users might not see the styles.
Weird browser bug? Possibly. Did we do something wrong? Maybe. Could we still log in? Absolutely.
