Accessibility guide

Accessibility is important. We want Trustroots to be inclusive and hence our websites have to be accessible to people whose abilities are limited in some way.

Generally speaking the status of the accessibility of Trustroots is currently unknown and should probably be assumed to be at bad state.

There’s lots to work on! This guide is to help navigate some of the basic concerns.

WACG 2.0

WCAG 2.0 is the main standard to follow but unfortunately the documentation at W3C is somewhat convoluted. That’s why we try to create a more readable overview of what we need to know to make and keep our site accessible to most people.

WCAG: three levels

Level A: eliminate major accessibility barriers.

Level AA: a very good level of accessibility.

Level AAA: very meticulous.

Trustroots should first get level A compliance, then work on AA and keep AA. AAA is probably a bit too far stretched.

WCAG: four principles

Principle 1: Perceivable

• Text Alternatives: e.g. alt attributes for images
• Time-based Media
• Adaptable
• Distinguishable

Principle 2: Operable

• Keyboard Accessible
• Enough Time
• Seizures
• Navigable

Principle 3: Understandable

• Readable
• Predictable
• Input Assistance

Principle 4: Robust

• Compatible
