bad87fee1348bd9aedf08845	Use a span to Target Inline Elements	0		使用跨度来定位内联元素

Description

您可以使用跨度来创建内联元素。还记得我们使用btn-block类使按钮填满整行吗？普通按钮 btn-block按钮说明“内联”元素和“块”元素之间的区别。通过使用内联span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span元素中的“Things cats love”元素中嵌入“love”这个词。然后给出span类text-danger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： <p>Top 3 things cats <span class="text-danger">hate:</span></p>

Instructions

Tests

tests:
  - text: 你的<code>span</code>元素应该在你的<code>p</code>元素中。
    testString: assert($("p span") && $("p span").length > 0);
  - text: 你的<code>span</code>元素应该只有文字<code>love</code> 。
    testString: assert($("p span") && $("p span").text().match(/love/i) && !$("p span").text().match(/Things cats/i));
  - text: 你的<code>span</code>元素应该有class <code>text-danger</code> 。
    testString: assert($("span").hasClass("text-danger"));
  - 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);
