Like headings, both types of lists are really great at making content easy to scan and helping readers take in information quickly. Bonus points if you keep ‘em short and to the point. We think of this as the “all killer, no filler” approach to content. You’ll hear more about that next time, when we talk about text and formatting.
When creating lists, check that you’re using the program’s built-in tools. Don’t use a dash or punctuation mark to represent a bullet, or type the numbers manually. Instead, let the program's tools do the formatting for you: it’s easier on you, makes your content easier to read, and supports those who use assistive technologies.
