Overview
Modern stylesheets utilize CSS custom properties, nested selectors, container queries, and preprocessor syntax. Legacy CSS beautifiers often fail when parsing modern features like @layer, @container, or color functions (oklch, color-mix).
DevFlow's CSS Formatter handles modern CSS3 and SCSS syntax, reformatting complex stylesheets into beautifully structured code.
