How It Works
The HTML Formatter parses your HTML input by tokenizing it into tags, text content, comments, and other elements. In beautify mode, it applies proper indentation based on the nesting level of elements, placing each tag on its own line for maximum readability.
Self-closing elements like <br>, <img>, and <input> are recognized and handled correctly without increasing indentation. In minify mode, all unnecessary whitespace, line breaks, and indentation are removed to produce the most compact output.
