• Pick a meaningful title for your pull request. (Use sentence case.)
  • Prefix the title with an emoji to identify what is being done. (Copy-paste the emoji itself (not the :code:) from the list below.)
  • Do not overuse punctuation in the title (like (chore):).
  • If it is helpful, use a simple prefix (like ProjectX: Implement some feature).
• Enter a succinct description that says why the PR is necessary, and what it does.
  • Mention the GitHub issue that is being addressed by the pull request.

• Improve accessibility by C
