The document provides guidelines for effectively using lists and tables on websites. It recommends using bulleted lists for items or options and numbered lists for instructions. Lists should be kept short, with 5-10 items for unfamiliar topics. List items should be formatted consistently and start the same way. Tables are best for comparing options with "if-then" relationships or numbers. The first column of a table needs careful consideration to clearly convey the questions being answered. Both lists and tables should be formatted neatly for easy reading.
