Creating Issues

Make sure to provide enough information to identify instances of text with poor contrast.
Your team may wish to list failures for all failings of a certain type of text (list text, navigation text, superscript text, etc.) in one issue.

Text has poor contrast

  • Description: Text has poor contrast
    • Describe the type of text (ex. call to action button text has poor contrast) or use actual words as they appear on the page (ex. "THIS IS MORE THAN SUMMER SHOPPING" text has poor contrast)
    • Since you have the color codes, it may be useful to provide that information as well (ex. light grey text (#777777) has poor contrast with its white background (#FFFFFF)
  • Priority: P2
  • Label or Tag: #a11y143
