# --description--
|
|
|
|
Continuando con el tema de fechas, HTML5 también introdujo el elemento `time` junto con un atributo `datetime` para estandarizar las horas. El elemento `time` es un elemento en línea que puede ajustar una fecha u hora en una página. Un atributo `datetime` contiene un formato válido para esa fecha. Este es el valor al que acceden los dispositivos de asistencia. Ayuda a evitar la confusión al declarar una versión estandarizada de un tiempo, incluso si está escrita informal o coloquialmente en el texto.
|
|
|
|
Aquí hay un ejemplo:
|
|
|
|
```html
|
|
<p>Master Camper Cat officiated the cage match between Goro and Scorpion <time datetime="2013-02-13">last Wednesday</time>, which ended in a draw.</p>
|
|
```
|
|
|
|
# --instructions--
|
|
|
|
¡Ya tenemos los resultados de la encuesta de Mortal Kombat de Camper Cat! Envuelve una etiqueta `time` alrededor del texto `Thursday, September 15<sup>th</sup>` y agregua un atributo `datetime` establecido en `2016-09-15`.
|
|
|
|
# --hints--
|
|
|
|
Tu código debe tener un elemento `p` que incluya el texto `Thank you to everyone for responding to Master Camper Cat's survey.` e incluya un elemento `time`.
|
|
|
|
```js
|
|
assert(timeElement);
|
|
```
|
|
|
|
Las etiquetas `time` añadidas deben envolver el texto `Thursday, September 15<sup>th</sup>`.
|
|
|
|
```js
|
|
assert(
|
|
timeElement &&
|
|
timeElement?.innerHTML?.trim() === 'Thursday, September 15<sup>th</sup>'
|
|
);
|
|
```
|
|
|
|
Tu etiqueta `time` agregada debe tener un atributo `datetime` que no esté vacío.
|
|
|
|
```js
|
|
assert(datetimeAttr && datetimeAttr?.length);
|
|
```
|
|
|
|
Tu atributo `datetime` agregado debe establecerse en un valor de `2016-09-15`.
|
|
|
|
```js
|
|
assert(datetimeAttr === '2016-09-15');
|
|
```
