Chat

There are 3 ways to chat with CodeRabbit:

• 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 generate unit testing code for this file.
  • @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.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

2-3: 布局调整解决了字数限制文本遮挡问题

通过将布局方式从绝对定位改为 flex 布局，并使用 flex-direction: column 确保字数限制文本正确放置在内容下方，解决了遮挡问题。同时新增的 text-align 属性提供了更灵活的对齐方式控制。

建议考虑添加一个小的间距，以优化视觉效果：

 &-limit {
   font-size: $textarea-font;
   color: $textarea-limit-color;
+  margin-top: 4px;
   text-align: $textarea-limit-align;
 }

Also applies to: 22-22
