Summary

The language selector inherits the white branded navbar color into its light popover, making the alternate language unreadable. Its upstream hover background also hides the white trigger icon. Use the theme's body color for the popover and the existing navbar hover surface for the trigger.

Validation

  • Strict production Hugo build
  • Link validation (bash dist/validate-links.sh)
  • Playwright language menu regression: English and Chinese home/docs pages, light and dark themes, hover, keyboard focus and navigation (8 cases)
  • Browser inspection and before/after screenshots

Summary by CodeRabbit

  • 样式改进

    • 优化首页和文档页的语言选择器样式,提升语言菜单文字的可读性。
    • 触发器在悬停或键盘聚焦时保持透明背景。
  • 测试

    • 增加语言菜单在中英文路由及浅色、深色主题下的显示、对比度和语言切换验证。

The styling change is mergeable with a bounded testing follow-up: calculate contrast against the effective menu background so future readability regressions are reliably detected.

请按实际合成背景计算菜单文字对比度。

当链接和 ul 都透明时,辅助函数会按透明黑计算对比度。白色文字可能通过 4.5:1 检查,即使实际页面背景较浅。请让辅助函数计算菜单及其祖先表面的有效背景,再执行对比度检查。
