Improved accessibility features in GitHub CLI

We’ve introduced new accessibility updates to the GitHub CLI, designed to make terminal workflows more inclusive for all developers. These improvements focus on:

  • Speech synthesis screen reader support: Enhanced prompting and progress indicators now provide better context and clarity for users relying on screen readers.
  • Color and contrast customization: Optimized color palettes ensure compatibility with terminal preferences, maintaining readability for users with low vision or colorblindness. Alignment with ANSI 4-bit color standards allows users to tailor their color usage to their needs.

These updates are available in public preview. To start using these features, run gh a11y.

To learn more, check out the GitHub CLI release notes for version 2.72.0.

New Default: Underlined Links for Improved Accessibility

By default, links within text blocks on GitHub are now underlined. This ensures links are easily distinguishable from surrounding text. If preferred, you can "hide" underlines for these links in the accessibility settings. More details can be found in the documentation – managing the appearance of links.

Should you encounter any issues with this feature during its public beta, please provide feedback.

Thanks for aiding our mission to enhance GitHub's accessibility!

Enhanced Accessibility for Links in Text Blocks Public Beta

To improve accessibility for our users, we've introduced a new accessibility setting to underline links within text blocks. Links should be easily distinguishable from surrounding text, not just by color but by styling. You can now toggle an accessibility setting to either "show" or "hide" underlines for links in text blocks, ensuring clear visibility and differentiation. You can learn more about this functionality in the documentation.

During this public beta phase, your feedback is invaluable. If you spot a link within a text block that isn’t underlined when the setting is enabled, please let us know.

Thank you for supporting our commitment to making GitHub more accessible for everyone!

Accessibility improvements for the contribution graph

The contribution graph now supports keyboard interaction and compatibility with assistive technologies. Users can navigate the graph and filter contributions using the keyboard. While navigating the graph, a summary of each day is displayed visually in a tooltip and announced by screen readers.

Users can move keyboard focus to the contribution graph and then navigate it using the following commands:

  • Press arrow keys to navigate cell by cell
  • Press Page Up to navigate to the first cell in a column
  • Press Page Down to navigate to the last cell in a column
  • Press Home to navigate to the first cell in a row
  • Press End to navigate to the last cell in a row
  • Press Enter to filter content in the Contribution Activity section by the current cell

If the user is running a screen reader, it will announce the following text when the graph receives keyboard focus:

Contribution Graph, table, 54 columns, 8 rows.
User activity over 1 year of time. Each column is one week, with older weeks to the left. Select a cell to filter the "Contribution Activity" section.

When the user navigates to a cell, the screen reader will read a summary such as:

11 contributions on Monday, February 21, 2022.

We are excited to make one of our favorite GitHub features available to more users! If you encounter any issues with these changes, please leave a reply on this feedback discussion.
