Say goodbye to complex developer consoles and manual styling math. Meet StyleTune—the ultimate visual CSS and typography sandbox designed specifically for UI/UX designers, No-Code creators (Webflow, Framer), and frontend developers [4]. Whether you are preparing a quick client demo, testing alternative design iterations, or preparing a design handoff, StyleTune gives you Figma-style control directly inside your browser [4]. ✦ KEY FEATURES FOR DESIGNERS: 🎨 VISUAL STYLE SANDBOX (Colors & Gradients) • Recolor any element on any live website with an intuitive color picker and eyedropper. • Fallback engine: Works smoothly on static, legacy, and utility-CSS (Tailwind) sites. • Advanced Gradient Engine: Craft complex linear or radial CSS gradients with multi-stop bars. • Hue Shift: Instantly rotate the entire page's color spectrum to explore alternative themes. 🔤 FIGMA-STYLE TYPOGRAPHY (Font Pairing & Sizes) • Tweak fonts, sizes, weights (100–900), and line heights visually on any webpage. • Font Pairing: Change all Headings and Body/UI text simultaneously to test pair aesthetics. • Upload Custom Fonts: Import your local .ttf or .woff2 files and make them available instantly (PRO). 🚀 ZERO-CODE STYLE HANDOFF • Skip the manual CSS copy-pasting routine. • Export clean, compiled CSS variables or custom Tailwind CSS configs in a single click. • Move your visual design choices straight into Webflow, Framer, or production code. 💾 LOCAL DESIGN PRESETS • Save your progress as custom presets. • Toggle between different design variations (e.g., "Variant A", "Dark Mode Concept") instantly. • Presets are locked per domain and saved safely. ✦ 100% PRIVATE & OFFLINE-FIRST We believe in ultimate privacy.
