Walkthrough

This update modifies the styling for the Tree Menu component. In the theme’s CSS files, new custom properties are introduced and applied to provide distinct color feedback for hovered and selected states of tree menu nodes. The changes involve updating both the node’s name hover color and the node’s body selected color, enhancing visual consistency in the tree menu.

Changes

Files	Change Summary
packages/theme/src/tree-menu/index.less, packages/theme/src/tree-menu/vars.less	Added new CSS custom properties and applied them to update the tree menu node colors. In index.less, the hover state of .tree-node-name now uses var(--tv-TreeMenu-node-name-hover-color) and the selected state of .tree-node-body uses var(--tv-TreeMenu-node-body-selected-color). In vars.less, new variables for these states are defined using existing color values.

Poem

I'm a rabbit, hopping by,
Through lines of code that catch the eye.
Hover hues and selected shades align,
In tree menus that now brightly shine.
I nibble bugs and cheer the change,
Code so spry, beyond the range!
🥕💻 Hop on and enjoy the vibe!

packages/theme/src/tree-menu/index.less (2)

216-219: Dark Theme Hover State Styling for Node Names
The new hover styling in the .tree-node-name selector now applies var(--tv-TreeMenu-node-name-hover-color), ensuring that hover interactions are clearly visible in dark mode. This change aligns well with the dark theme update objective.

---

254-258: Dark Theme Selected State Styling Update
The update in the .is-current block now uses var(--tv-TreeMenu-node-body-selected-color) for the .tree-node-body, which provides a clear visual cue for selected nodes in dark mode. This improves the consistency of the theme and meets the de#tent described in the PR.

packages/theme/src/tree-menu/vars.less (1)

80-83: Introduction of Dark Theme CSS Custom Properties
The new CSS variables --tv-TreeMenu-node-body-selected-color and --tv-TreeMenu-node-name-hover-color are correctly defined, pulling values from existing design tokens (var(--tv-color-border-active) and var(--tv-color-border-hover)). This approach is clean and ensures consistent theming across the tree menu component.
