<samp>:样本输出元素
<samp>
HTML 元素用于包含表示计算机程序的示例(或引用)输出的内联文本。其内容通常使用浏览器的默认等宽字体(例如 导游 或 Lucida Console)呈现。
¥The <samp>
HTML element is used to enclose inline text which represents sample (or quoted) output from a computer program. Its contents are typically rendered using the browser's default monospaced font (such as Courier or Lucida Console).

使用说明
¥Usage notes
你可以使用 CSS 规则来覆盖浏览器的 <samp>
元素的默认字体;但是,浏览器的首选项可能优先于你指定的任何 CSS。
¥You can use a CSS rule to override the browser's default font face for the <samp>
element; however, it's possible that the browser's preferences may take precedence over any CSS you specify.
覆盖默认字体的 CSS 如下所示:
¥The CSS to override the default font face would look like this:
samp {
font-family: "Courier";
}
注意:如果你需要一个元素作为网站或应用的 JavaScript 代码生成的输出的容器,则应使用
<output>
元素。¥Note: If you need an element which will serve as a container for output generated by your website or app's JavaScript code, you should instead use the
<output>
element.
示例
基本示例
¥Basic example
在这个简单的示例中,一个段落包含程序输出的示例。
¥In this simple example, a paragraph includes an example of the output of a program.
<p>
When the process is complete, the utility will output the text
<samp>Scan complete. Found <em>N</em> results.</samp> You can then proceed to
the next step.
</p>
结果
¥Result
包括用户输入的示例输出
¥Sample output including user input
你可以将 <kbd>
元素嵌套在 <samp>
块中以呈现包含用户输入的文本的示例。例如,考虑此文本显示 Linux(或 macOS)控制台会话的记录:
¥You can nest the <kbd>
element within a <samp>
block to present an example that includes text entered by the user. For example, consider this text presenting a transcript of a Linux (or macOS) console session:
HTML
<pre>
<samp><span class="prompt">mike@interwebz:~$</span> <kbd>md5 -s "Hello world"</kbd>
MD5 ("Hello world") = 3e25960a79dbc69b674cd4ec67a72c62
<span class="prompt">mike@interwebz:~$</span> <span class="cursor">█</span></samp></pre>
请注意,使用 <span>
可以自定义示例文本特定部分的外观,例如 shell 提示和光标。另请注意,使用 <kbd>
来表示用户在示例文本中的提示符处输入的命令。
¥Note the use of <span>
to allow customization of the appearance of specific portions of the sample text such as the shell prompts and the cursor. Note also the use of <kbd>
to represent the command the user entered at the prompt in the sample text.
CSS
实现我们想要的外观的 CSS 是:
¥The CSS that achieves the appearance we want is:
.prompt {
color: #b00;
}
samp > kbd {
font-weight: bold;
}
.cursor {
color: #00b;
}
这为提示和光标提供了相当微妙的着色,并增强了示例文本中的键盘输入。
¥This gives the prompt and cursor fairly subtle colorization and emboldens the keyboard input within the sample text.
结果
¥Result
结果输出是这样的:
¥The resulting output is this:
