Computer Code Elements

The computer has a unique formatting and text style for showing code-related messages. The <code> tag is utilised to show the computer code on the website. 

There are many elements available to mark up computer code using HTML.

<code> Tag 

The <code> tag in HTML represents the piece of computer code. 

While building web pages, occasionally, there is a need to display computer programming code. It could be accomplished by any basic heading tag of HTML, but HTML delivers a particular tag which is <code> tag.

The code tag is a specific type of text which describe computer output. HTML delivers many ways for text formatting, but <code> tag is shown with fixed letter size, font, and spacing.

Syntax: 

<code> Computer code contents... </code>{alertSuccess}
 

Example 1: 
 
<pre>
<code>
#include<stdio.h>
int main() {
    printf("Hello A.T");
}
</code>
</pre>{codeBox}

Example 2: 
 
<pre>
<code>
class AT
    // Program begins with a call to main()
    // Print "Hello, World" to the terminal window 
    public static void main(String args[]) 
    { 
        System.out.println("Hello, World"); 
    } 
</code>
</pre>{codeBox}

Note: The program written inside the <code> tag has different font sizes and font types to the basic heading tag and paragraph tag. <pre> tag is utilised to show code snippets because it consistently keeps the text formatting as it is.{alertError}

Some points about <code> tag: 

  • It is mostly utilised to show the code snippet in the web browser.
  • This tag styles its element to match the computer’s default text format.
  • The web browsers, by default, use a monospace font family for showing <code> tags element content

<kbd> Tag

It is a phrase tag & utilised to define the keyboard input. The text between the <kbd> tag symbolises similar text that should be typed on the keyboard.

Syntax: 

<kbd> Contents... </kbd>{alertSuccess}

Example: 
 
<!DOCTYPE html>
<html>

<head>
<title>The kbd tag</title>
<style>
body {
text-align: center;
}
</style>
</head>

<body>
<div class="AT">AKASHTIMES</div> 
<kbd>A computer</kbd> 
<kbd>science</kbd> 
<kbd>portal</kbd> 

</body>
</html>{codeBox}

Some points about <kbd> tag: 

  • The text enclosed by <kbd> tag is typically shown in the browser’s default mono-space font.

Text in the <pre> element is shown in a fixed-width font, but it can be modified using CSS. The <pre> tag needs a starting and end tag.

<!DOCTYPE html>
<html>

<head>
<title>pre tag</title>
</head>

<pre>
    // Program begins with a call to main()
    // Print "Hello, World" to the terminal window 
    public static void main(String args[]) 
    { 
        System.out.println("Hello, World"); 
    } 
}

        </pre>

            }
        </style>

<pre>
    // Program begins with a call to main()
    // Print "Hello, World" to the terminal window 
    public static void main(String args[]) 
    { 
        System.out.println("Hello, World"); 
    } 
}

        </pre> 

</body>
</html>{codeBox}
