## Description
|
||
<section id="description"> HTML5引入了<code>figure</code>元素以及相关的<code>figcaption</code> 。这些项目一起使用，包含可视化表示（如图像，图表或图表）及其标题。通过语义分组相关内容和提供解释<code>figure</code>的文本替代，这提供了双倍的可访问性提升。对于图表等数据可视化，可以使用标题简要说明视力障碍用户的趋势或结论。另一个挑战包括如何为屏幕阅读器用户在屏幕外（使用CSS）移动图表数据的表格版本。这是一个例子 - 请注意， <code>figcaption</code>位于<code>figure</code>标签内部，可以与其他元素组合： <blockquote> <图> <br> <img src =“roundhouseDestruction.jpeg”alt =“露营猫执行圆屋踢的照片”> <br>点击<br> <figcaption> <br> Master Camper Cat展示了适当形式的圆屋踢。 <br> </ figcaption> <br> </图> <br></blockquote></section>

## Instructions
|
||
<section id="instructions"> Camper Cat正在努力创建一个堆积条形图，显示每周花在隐形，战斗和武器上的训练时间。通过将用于<code>figure</code>标记的<code>div</code>标签和包含标题的<code>p</code>标签更改为<code>figcaption</code>标记，帮助他更好地构建页面。 </section>

|
||
- text: 确保您的<code>figure</code>元素有一个结束标记。
|
||
testString: 'assert(code.match(/<\/figure>/g) && code.match(/<\/figure>/g).length === code.match(/<figure>/g).length, "Make sure your <code>figure</code> element has a closing tag.");'
