bad87fee1348bd9aedf08845	0	18370	使用 span 创建行内元素

Description

你可以使用 span 标签来创建行内元素。还记得我们怎么使用 btn-block class 来创建填满整行的按钮吗？ normal button btn-block button 上面的例子就是 "inline" （行内）元素和 "block" （块级）元素的区别。通过使用行内元素 span，你可以把不同的元素放在同一行，甚至能为一个元素的不同部分指定样式。把 "Things cats love" 中的 "love" 放入 span 标签。然后为其添加 text-danger class 来使其文字变成红色。 "Top 3 things cats hate" 元素的写法如下： <p>Top 3 things cats <span class="text-danger">hate:</span></p>

Instructions

Tests

tests:
  - text: <code>span</code> 元素应该在 <code>p</code> 元素内。
    testString: assert($("p span") && $("p span").length > 0);
  - text: <code>span</code> 元素应该只含有文本 <code>love</code>。
    testString: assert($("p span") && $("p span").text().match(/love/i) && !$("p span").text().match(/Things cats/i));
  - text: <code>span</code> 元素应该含有 class <code>text-danger</code>。
    testString: assert($("span").hasClass("text-danger"));
  - text: 确保你的 <code>span</code> 元素有一个闭合标签。
    testString: assert(code.match(/<\/span>/g) && code.match(/<span/g) && code.match(/<\/span>/g).length === code.match(/<span/g).length);
