Dos and Dont's

What we talk about when we talk about accessibility

Accessibility is more than just color contrast. We believe in designing for each user, not just “all users”. We build with these considerations in mind:

  • Screen magnification, voice dictation, color blindness, and those who require help with fine motor control.
  • Semantic HTML to better communicate with assistive technologies.
  • UI controls that are designed to be instantly recognizable and easy to see.
  • Keyboard navigation and focus management to allow task completion through a variety of input devices.
