## Description
<section id="description">您可以使用跨度来创建内联元素。还记得我们使用<code>btn-block</code>类使按钮填满整行吗？ <button class="btn" style="background-color: rgb(0, 100, 0);  color: rgb(255, 255, 255);">普通按钮</button> <button class="btn btn-block" style="background-color: rgb(0, 100, 0);  color: rgb(255, 255, 255);">btn-block按钮</button>说明“内联”元素和“块”元素之间的区别。通过使用内联<code>span</code>元素，您可以将多个元素放在同一行上，甚至可以不同地为同一行的不同部分设置样式。在<code>span</code>元素中的“Things cats love”元素中嵌入“love”这个词。然后给出<code>span</code>类<code>text-danger</code>以使文本变为红色。以下是你如何使用“猫讨厌的三件事”元素： <code>&lt;p&gt;Top 3 things cats &lt;span class=&quot;text-danger&quot;&gt;hate:&lt;/span&gt;&lt;/p&gt;</code> </section>

## Tests

```yml
tests:
  - text: 你的<code>span</code>元素应该在你的<code>p</code>元素中。
    testString: 'assert($("p span") && $("p span").length > 0, "Your <code>span</code> element should be inside your <code>p</code> element.");'
  - text: 你的<code>span</code>元素应该只有文字<code>love</code> 。
    testString: 'assert($("p span") && $("p span").text().match(/love/i) && !$("p span").text().match(/Things cats/i), "Your <code>span</code> element should have just the text <code>love</code>.");'
  - text: 你的<code>span</code>元素应该有class <code>text-danger</code> 。
    testString: 'assert($("span").hasClass("text-danger"), "Your <code>span</code> element should have class <code>text-danger</code>.");'
  - text: 确保您的<code>span</code>元素具有结束标记。
    testString: 'assert(code.match(/<\/span>/g) && code.match(/<span/g) && code.match(/<\/span>/g).length === code.match(/<span/g).length, "Make sure your <code>span</code> element has a closing tag.");'
