About HTML/CSS Beautifier
HTML/CSS Beautifier reformats messy, minified, or inconsistently indented HTML and CSS into clean, properly nested, readable code. It's useful when you've copied minified code from a live website and need to actually read it, when a teammate's code has inconsistent indentation, or when you're debugging a layout issue and need the structure to be visually clear rather than one long unreadable line.
