# Issue Priorities

## P1 Issues

A barrier that makes completion of a task impossible for some users.

### Examples that can create a P1 issue

* Keyboard focus trapped
  * Why: User cannot proceed backwards or forwards through page
* Interactive element not operable with keyboard alone
  * Why: User cannot complete a primary task (e.g "Buy it Now",  "Submit Form")
* Element with misleading accessible label
  * Why: User might make an action they did not intend, with dangerous consequences (e.g. a "Submit Payment" button programmatically labelled as "Review Payment")

## P2 Issues

A barrier that makes completion of a task difficult for some users.

### Examples that can create a P2 issue

* Pinch-to-zoom disabled
  * Workaround: User must use non-standard magnifying software to resize text
* Form field lacking a visible or programmatic label
  * Workaround: User must explore adjacent elements to determine context
* Color contrast below the contrast minimum
  * Workaround: User must provide a custom stylesheet to make text/graphics legible
* Document missing semantic heading structure
  * Workaround: User must read entire page content to form mental model

## P3 Issues

A barrier that makes completion of a task tedious or annoying for some users.

### Examples that can create a P3 issue

* Keyboard focus indicator missing on element, but present on adjacent elements
  * Workaround: User can determine focus by navigating through surrounding elements
* Keyboard focus indicator does not go where the user expects
  * Workaround: user has to discover how to get focus where they expect it to be
* Widget interaction different from the established pattern
  * Workaround: User has to learn multiple of the same type of widget and then figure out which they're using each time
* Page missing "Skip to Main"
  * Workaround: User has to navigate through all repeated header elements on every page
* Redundant labeling on a button, link, or input
  * Workaround: User has to listen through extraneous information

## P4 Issues

A non-barrier that technically fails accessibility guidelines.

### Examples that can create a P4 issue

* Non-unique IDs on unreferenced elements
* Duplicate attributes with identical value
* Non-escaped attribute values
