Step-by-step instructions

  1. Type this message and press Return:
Codex message

Please improve the appearance of my task-list page without changing any features. Use a calm, simple design with plenty of space, easy-to-read text, a clear Add Task button, and a neat task list. Keep it comfortable to use on both a computer and a phone. Tell me exactly what to look for when I refresh the page.

  1. Refresh the page and look at the heading, task box, buttons, and task list.
  2. Add a task, mark it finished, remove it, and refresh the page.

How to check it worked: The page is clear and easy to read, and every earlier feature still works.

If something doesn't work

Codex message

The page looks better, but I can no longer add a task. Please fix just that one problem without changing the design.

What just happened?

Codex changed the visual instructions for the page: spacing, colours, text size, and layout. These changes affect how the page looks rather than what your task list does.

You checked the features again because appearance changes can accidentally affect a working control. Checking after every meaningful change is what keeps the app reliable.

Module checklist

  • The page is easy to read.
  • Controls are easy to find.
  • Adding, finishing, removing, and refreshing still work.

Next module: You will test the app like a real user.
