「校验」会用浏览器原生解析器检查标签是否闭合、结构是否合法，出错时提示行列位置。「格式化」按所选缩进重新排版；「压缩」去掉多余空白，便于传输或嵌入。输入时会自动实时格式化预览。Validate uses the browser's native parser to check tag balance and structure, reporting the error line/column. Format re-indents to your chosen width; Minify strips extra whitespace. Typing auto-formats a live preview.
