HTML Computer Code Elements

Introduction:

HTML offers several elements specifically for displaying computer code, providing necessary formatting to maintain readability of code snippets. The most commonly used elements for this purpose include <code>, <pre>, <samp>, <kbd>, and <var>.

Key Code Elements:

1. <code>

Used to denote inline code snippets and commands.

    <p>To display a piece of code inline, use the <code>code</code> tag.</p>
                

2. <pre>

Preserves white space and formatting in its content, often used in conjunction with <code>.

    <pre>
    <code>
    function helloWorld() {
        console.log("Hello, World!");
    }
    </code>
    </pre>
                

3. <samp>

Used to represent output from a computer program.

    <p>Output: <samp>Login successful!</samp></p>
                

4. <kbd>

Represents user input, like keyboard strokes.

    <p>To save a file, press <kbd>Ctrl</kbd> + <kbd>s</kbd>.</p>
                

5. <var>

Used for defining variables in computer programming or mathematical expressions.

    <p>The quadratic formula: <var>a</var>x² + <var>b</var>x + <var>c</var> = 0</p>
