El atributo lang de HTML se puede usar para declarar el idioma de una página web o parte de una página web. Esto es útil para los motores de búsqueda y los navegadores.
Basado en W3C Recomendaciones estándar, debe declarar el idioma principal de cada página en el atributo lang del etiqueta <html>, por ejemplo:
<html lang="en">
...
</html>
En XHTML, se declara el idioma en la etiqueta <html> de la siguiente manera:
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
...
</html>
ISO 639-1 Se han definido abreviaturas para varios idiomas. Pueden usarse en las propiedades lang y xml:lang de HTML y XHTML.
