# Phase 9: Calendar CSS (`styles.css`)

**Status:** Not started
**Depends on:** Phase 3 (calendar-renderer.ts — must match the CSS classes used in rendering)
**Modifies:** `styles.css`

---

## Overview

Append calendar styles to the plugin's stylesheet. Use Obsidian CSS variables for theme compatibility (light/dark).

## Notes

- Use `var(--background-primary)`, `var(--text-normal)`, `var(--interactive-accent)`, etc. for theme compatibility.
- The grid should be responsive within the sidebar width.
- Day cells should have consistent sizing — use CSS Grid with `grid-template-columns: repeat(7, 1fr)` (or 8 when week numbers are shown).
- Today highlight should use `var(--interactive-accent)` with reduced opacity for the background.
- "has-note" dots should be small circles below the day number.
- "other-month" days should have reduced opacity.
- "active" day should have a distinct border or background to show it's the currently open note.
