Walkthrough

A new "提示" (Tip) section has been added to the Tailwind CSS documentation. The update explains that Tailwind CSS has advanced to version 4.x, which differs from version 3.4.17 and is incompatible with older 3.x releases. It also advises users to verify the tailwindcss version in their package.json. No changes were made to any exported or public entities.

Poem

I'm a rabbit on the run,
Hopping through docs under the sun.
A new tip appears with a joyful leap,
Guiding code changes to soar and keep.
With Tailwind 4.x in the mix so bright,
I celebrate these changes with pure delight!

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:

  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  • @coderabbitai read src/utils.ts and generate unit testing code.
