在HTML中，对用户输入，代码，程序等会使用不同的标签来显示，这些计算机代码元素分别为：元素、元素、元素、<pre class="brush:php;toolbar:false">元素、<var>元素；这些计算机代码元素支持固定的字母尺寸和间距。本篇文章就给大家介绍一下HTML的计算机代码元素，希望对你们有所帮助。</var></pre>
HTML 元素
元素是用于表示用户输入，键盘输入，语音命令等，它经常被用于和计算机相关的文档和手册中。被包含在 ..... kbd>标签内的文本通常是以浏览器的默认等宽字体显示。下面我们来看看示例：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<h2 id="kbd标签元素">kbd标签元素</h2>
<p> <kbd>这就是在kbd元素中写入的内容的样子。</kbd></p><br>
<h4 id="kbd标签元素经常被用于和计算机相关的文档和手册中">kbd标签元素经常被用于和计算机相关的文档和手册中</h4>
<p>键入 <kbd>quit</kbd> 来退出程序，或者键入 <kbd>menu</kbd> 来返回主菜单。</p>
</body>
</html>效果图：
HTML 元素
元素是用于表示程序的输出（一段用户应该对其没有什么其他解释的文本字符）。被包含在元素中编写的文本通常是以浏览器的默认等宽字体显示。下面我们来看看示例：
<h2 id="samp标签元素">samp标签元素</h2> <p> <kbd>这就是在samp标签元素中写入的内容的样子。</kbd></p>
效果图：
HTML 元素
元素是用于表示一些编程代码（计算机源代码或者其他机器可以阅读的文本内容），它是为软件代码的编写者设计的；被包含在<code>元素中编写的文本将用等宽、类似电传打字机样式的字体（Courier）显示出来。下面我们来看看示例：
<h2 id="计算机代码">计算机代码</h2> <p>这是一个编程代码：</p> <code> x = 5;<br> y = 6;<br> z = x + y; </code>
效果图：
HTML 元素
元素可定义预格式化的文本，可用来表示计算机的源代码。被包含在<pre class="brush:php;toolbar:false">元素中的文本会严格限制为等宽字体格式。下面我们来看看示例：<pre class='brush:php;toolbar:false;'><pre class="brush:php;toolbar:false"> <!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body> <p>pre标签元素</p> </body> </html>
在上面的代码中，
标签中的特殊符号被转换为符号实体，比如 "" 代表 ">"。下面我们来看看效果：<p style="text-align: center;"><img src="/static/imghwm/default1.png" data-src="https://img.php.cn//upload/image/554/268/746/1545189772817296.jpg?x-oss-process=image/resize,p_40" class="lazy" title="1545189772817296.jpg" alt="What are the computer code elements of html"></p><p><span style="max-width:90%">说明：</span>虽然<code>元素和<pre class="brush:php;toolbar:false"> 元素都是可以以等宽字体格式显示编程代码，但它们之间还是有差异的：
元素内的文本显示不保留多余的空格和折行；但在 pre 元素中的文本通常会保留空格和换行符。
我们来看看区别效果：
<p>code标签</p>
<code>
var student = {
学号："01"
姓名:"小华"
}
</code>
<p>pre标签</p>
<pre class="brush:php;toolbar:false">
var student = {
学号："02"
姓名:"小明"
}
效果图：
HTML 元素
元素用于定义变量。变量可以是数学表达式中的变量，也可以是编程上下文中的变量。下面我们来看看示例：
<h2 id="var元素">var元素</h2> <p>这是一个著名的公式： <var>E</var> = <var>mc</var><sup>2</sup>.</p>
效果图：
