Some users' browsers set default page colors that aren't black-on-white. For instance, Linux users who enable GTK style overrides might default to having white text on a dark background. Websites that explicitly set foreground colors but leave the default background color (or vice-versa) end up being difficult to read. The same phenomenon occurs on pages with text foregrounds with image backgrounds. Some users' browsers set default page colors that aren't black-on-white.

Some reading-mode implemen&shy;tations also support [DPUB-ARIA](https://www.w3.org/TR/dpub-aria-1.1/), but I'd caution against using ARIA when POSH is sufficient: "bad ARIA" can be far more harmful to screen readers than "no ARIA". Only use ARIA to fill in gaps left by POSH.

Reading modes aren't the only non-browser user agents out there. Plain-text feed readers and link previewers are some other options. I singled out reading modes because of their widespread adoption and value. Decide which other kinds of agents are important to you (if any), and see if they expose a hole in your semantics.

Consider the implications of translating between left-to-right (LTR) and right-to-left (RTL) languages. Do a search through your stylesheets for keywords like "left" and "right" to ensure that styles don't depend too heavily on text direction.
