I think you're misunderstanding something, though I can't pinpoint what it is. > The author is using something that manipulates the style of inputs to make them dark with light fonts The author is setting his system theme to a dark one. Maybe you don't know what that is because such options seem to be disappearing, but a system theme controls the styling of (ideally) all GUI applications running in the OS. One of these applications is the web browser. > but only if the input isn't explicitly styled with either background-color or color No, themes set both. It's the web developer that overrode one but not the other and what the author is complaining about. > If they're going to be doing such hackery, just style both at the same time. This is precisely what the author wishes of web developers and their hackery. You're directing this suggestion to the wrong person. The author did set both when setting his system theme. > Use JavaScript or something to ensure both are styled. This really isn't the developer's concern. Again, the author did style both when setting his system theme. It's the web developer that is overriding the style of one but not the other.
