2 min readJul 3, 2021
- Can the website be accessed without mouse, keyboard only?
- All images should have a reasonable alt tag
- Perceivable — Information and user interface components must be presentable to users in ways they can perceive.
This means that users must be able to perceive the information being presented (it can’t be invisible to all of their senses)
Provide text alternatives for non-text content.
Provide captions and other alternatives for multimedia.
Create content that can be presented in different ways, including by assistive technologies, without losing meaning.
Make it easier for users to see and hear content. - Operable — User interface components and navigation must be operable.
This means that users must be able to operate the interface (the interface cannot require interaction that a user cannot perform)
Make all functionality available from a keyboard.
Give users enough time to read and use content.
Do not use content that causes seizures.
Help users navigate and find content. - Understandable — Information and the operation of user interface must be understandable.
This means that users must be able to understand the information as well as the operation of the user interface (the content or operation cannot be beyond their understanding)
Make text readable and understandable.
Make content appear and operate in predictable ways.
Help users avoid and correct mistakes. - Robust — Content must be robust enough that it can be interpreted reliably by a wide variety of user agents, including assistive technologies.
This means that users must be able to access the content as technologies advance (as technologies and user agents evolve, the content should remain accessible)
Maximize compatibility with current and future user tools.
