| # --description--
 | |
| 
 | |
| El siguiente elemento HTML5 que agrega significado semántico y mejora la accesibilidad es la etiqueta `header`. Se usa para envolver información introductoria o enlaces de navegación para su etiqueta principal y funciona bien con el contenido que se repite en la parte superior en varias páginas.
 | |
| 
 | |
| `header` comparte la función landmark integrada que viste con `main`, lo que permite a las tecnologías de asistencia navegar rápidamente a ese contenido.
 | |
| 
 | |
| **Nota:** El `header` está diseñado para usarse dentro de la etiqueta `body` de tu documento HTML. Es diferente al elemento `head`, que contiene el título de la página, la meta información, etc.
 | |
| 
 | |
| # --instructions--
 | |
| 
 | |
| Camper Cat está escribiendo algunos grandes artículos sobre el entrenamiento ninja, y quiere añadir una página para ellos a su sitio. Cambia la parte superior `div` que actualmente contiene el `h1` a una etiqueta `header`.
 | |
| 
 | |
| # --hints--
 | |
| 
 | |
| Tu código debe tener una etiqueta `header`.
 | |
| 
 | |
| ```js
 | |
| assert($('header').length == 1);
 | |
| ```
 | |
| 
 | |
| Tus etiquetas `header` deben envolver `h1`.
 | |
| 
 | |
| ```js
 | |
| assert($('header').children('h1').length == 1);
 | |
| ```
 | |
| 
 | |
| Tu código no debe tener ninguna etiqueta `div`.
 | |
| 
 | |
| ```js
 | |
| assert($('div').length == 0);
 | |
| ```
 | |
| 
 | |
| Tu elemento `header` debe tener una etiqueta de cierre.
 | |
| 
 | |
| ```js
 | |
| assert(
 | |
|   code.match(/<\/header>/g) &&
 | |
|     code.match(/<\/header>/g).length === code.match(/<header>/g).length
 | |
| );
 | |
| ```
