localeTitle: 使用 HTML5 的 datatime 属性标准化时间
|
||
|
|

|
## Description
|
||
|
|
<section id='description'>
|
||
|
|
继续日期主题。HTML5 还引入了<code>time</code>标签与<code>datetime</code>属性来标准化时间。<code>time</code>是一个行内标签，用于在页面中呈现日期或时间，而<code>datetime</code>属性保存了日期的有效格式，辅助设备可以访问这个值。通过标准化时间格式，即使时间在文本中是以非正式的或口语化的形式编写，辅助设备依然可以获取准确的时间和日期。
|
||
|
|
举个例子：
|
||
|
|
<code><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></code>
|

|
## Instructions
|
||
|
|
<section id='instructions'>
|
||
|
|
Camper Cat 的比武大会的时间确定了！请使用<code>time</code>标签包含文本 "Thursday, September 15<sup>th</sup>"，并将<code>datetime</code>属性设置为 "2016-09-15"。
