HTML Computer Code Elements
HTML contains several elements for defining user input and computer code.
HTML <kbd> For Keyboard Input
The HTML <kbd> element is used 
to define keyboard input. The content inside is displayed in the browser's 
default monospace font.
Example
Define some text as keyboard input in a document:
<p>Save the document by pressing <kbd>Ctrl + S</kbd></p>
Result:
HTML <samp> For Program Output
The HTML <samp> element is used to 
define sample output from a computer program. The content inside is displayed in 
the browser's default monospace font.
Example
Define some text as sample output from a computer program in a document:
  <p>Message from my computer:</p>
<p><samp>File not found.<br>Press F1 to 
  continue</samp></p>
Result:
File not found.
Press F1 to continue
HTML <code> For Computer Code
The HTML <code> element  is used 
to define a piece of computer code. The content inside is displayed in the 
browser's default monospace font.
Example
Define some text as computer code in a document:
  <code>
x = 5;
y = 6;
z = x + y;
</code>
Result:
  x = 5;
  y = 6;
  z = x + y;
Notice that the <code> element does not preserve extra whitespace and line-breaks.
To fix this, you can put the <code> element inside a <pre> element:
Example
 <pre>
<code>
x = 5;
y = 6;
z = x + y;
</code>
</pre>
Result:
x = 5;
y = 6;
z = x + y;
HTML <var> For Variables
The HTML <var> element  is used 
to define a variable in programming or in a mathematical expression. The 
content inside is typically displayed in italic.
Example
Define some text as variables in a document:
  <p>The area of a triangle is: 1/2 x <var>b</var> x <var>h</var>, where <var>b</var> 
  is the base, and <var>h</var> is the vertical height.</p>
Result:
