| ## Description
 | ||
| <section id="description">当我们开始使用jQuery时,我们将修改HTML元素,而无需在HTML中实际更改它们。让我们确保每个人都知道他们不应该直接修改任何代码。请记住,您可以使用<code><!--</code>开始发表评论并使用<code>--></code>在HTML顶部添加评论“ <code>Only change code above this line.</code> </section>

|

| ```yml
 | ||
| tests:
 | ||
|   - text: 在HTML的顶部用<code><!--</code>开始评论。
 | ||
|     testString: 'assert(code.match(/^\s*<!--/), "Start a comment with <code><!--</code> at the top of your HTML.");'
 | ||
|   - text: 您的评论应该包含<code>Only change code above this line</code>的文本。
 | ||
|     testString: 'assert(code.match(/<!--(?!(>|->|.*-->.*this line))\s*.*this line.*\s*-->/gi), "Your comment should have the text <code>Only change code above this line</code>.");'
 | ||
|   - text: 请务必使用<code>--></code>关闭您的评论。
 | ||
|     testString: 'assert(code.match(/-->.*\n+.+/g), "Be sure to close your comment with <code>--></code>.");'
 | ||
|   - text: 你应该有相同数量的评论开启者和关闭者。
 | ||
|     testString: 'assert(code.match(/<!--/g).length === code.match(/-->/g).length, "You should have the same number of comment openers and closers.");'
