Description
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") && $("p span").length > 0, "Your <code>span</code> element should be inside your <code>p</code> element.");'
  - text: 你的<code>span</code>元素应该只有文字<code>love</code> 。
    testString: 'assert($("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.");'
