24 Ways (2019)

First initiated by Drew McLellan, 24 ways started out as a simple website that published a new tip or trick each day leading readers through December up until Christmas.

A11y Advent Calendar (2020)

Heydon Pickering once said, “Accessibility is not about doing more work but about doing the right work.” In 2020, Kitty Giraudel decided to publish an accessibility tip a day in their very own #A11yAdvent.
