Walkthrough

The changes involve updates to CSS variables within the .inject-CascaderNode-vars() function in the vars.less file. Two specific variables have been modified: the text color for selectable items has been changed to a new active color, and the font weight for highlighted items has been altered from regular to bold. These modifications impact the visual styling of the Cascader Node component, particularly in hover states and active item presentation.

Poem

🐰 In the garden where colors play,
Cascader nodes dance in a bold array.
Text shines bright, a lovely hue,
With every hover, a fresh debut.
Font weight strong, like a rabbit's cheer,
Styling changes bring us near! 🌼

51-51: LGTM! Enhanced visual hierarchy.

Changing the font weight from regular (400) to semi-bold (600) for active nodes improves the visual hierarchy and makes the selected state more prominent while maintaining readability.

  • @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.
