Rulesets Canvas
Every ruleset is a visual node. Nested selectors are indented automatically. Drag to reorder, double-click to rename, and ⇧ or ⌘-click to select multiple nodes at once.
Code Editor
Full syntax-aware code view. Switch tabs and your cursor position syncs back to the selected ruleset or variable.
Variables Panel
All CSS custom properties grouped by ruleset with collapsible sections. Edit names and values inline, drag to reorder, and see color swatches with live var() resolution.
Property Editor
Click any node to edit its properties with autocomplete, color pickers, and a variable picker. Select multiple nodes to view and batch-edit their shared properties simultaneously.
Multi-file Projects
Open a folder and browse all your CSS files in the sidebar. Create, rename, duplicate, and delete files without leaving the app.
Full Undo / Redo
Every action — edits, renames, reorders, color changes, additions, and deletions — is undoable and redoable.
