StyleBop is a visual editor for CSS files. Open a folder, get a clean canvas of every ruleset, edit colors and gradients with real pickers, build keyframe animations on a timeline, and manage design tokens across files. It writes plain CSS to disk. No proprietary format, no build step, no lock-in. Open the same folder in any other editor and the diffs are clean. What's inside • Rulesets canvas — every CSS selector becomes a node you can click into. Edit properties with type-aware popovers: color picker, gradient builder, box-shadow stack, cubic-bezier curve editor, grid template, filter chain. • Tokens tab — your :root custom properties and @font-face families in one place. Each variable has a usage tracker that shows every file and ruleset that consumes it. "0 references — safe to delete" so dead tokens stop accumulating. • Animations tab — keyframe timeline with draggable stops, live preview running on the canvas, cubic-bezier curve editor. • Code tab — full text view with autocompletion, smart typing (paste a hex on a color: line and it just works), and project-wide find/replace. • Extract to Variable — pick any literal value, hit a shortcut, and StyleBop rewrites every matching occurrence across the entire project to var(--name). Suggested names use a curated palette so #6495ED becomes --color-cornflower instead of --color-6495ed. Modern CSS @layer cascade layers, @container container queries, @supports feature queries, @media wrappers, CSS nesting, @keyframes, @font-face — all parsed as first-class constructs and round-tripped byte-perfect on save. Tailwind v4 @theme blocks are recognized as design-token surfaces. Tailwind-style files get Tailwind-style suggestions on Extract to Variable (--color-blue-500 instead of --color-cornflower), and new tokens land inside the existing @theme block. Localized UI in eleven languages: English, Spanish, French, German, Italian, Brazilian Portuguese, Japanese, Korean, Ukrainian, Russian, Simplified Chinese. Editor integrations Right-click any CSS file in VS Code or a JetBrains IDE and pick "Open in StyleBop" — the app launches and lands on the construct your cursor was on. Free companion extensions on the VS Code Marketplace and JetBrains Marketplace.

What's new in 2.1: • Text size — View ▸ Bigger / Smaller (⌘+ / ⌘−) or the slider in Settings scales text across the whole app, from 85% to 250%. • APCA contrast — the color picker shows APCA readings alongside the WCAG 2 ratios. • VoiceOver and Voice Control — every canvas card, property, variable, swatch and popover now has proper names and actions, and every reorderable list has Move Up / Move Down. • Reduce Motion — easing and animation previews stop looping and offer a one-shot Play button. • Higher contrast in the code editor and panels; contrast badges show a check or cross, not just color. • Unsaved edits — a blue dot marks any property or variable that differs from disk; right-click ▸ Revert to Saved undoes just that one. • The color notation switcher is now a pop-up menu. • Fixed: nested at-rules and Windows line endings could corrupt the canvas; Live Preview no longer mixes in styles from unrelated files; save errors are no longer silent. Sandboxed and signed. No tracking, no telemetry.
