The <code> tag in HTML is used to display a single line of computer code or a code snippet within text. It is typically used to present code within paragraphs, sentences, or other inline content. The <code> tag is a semantic element that helps differentiate code from regular text and maintains proper formatting for readability.

Syntax:

<p>Use the <code>print()</code> function to output text in Python.</p>

Key Characteristics:

1. Inline Formatting: The <code> tag is an inline element, meaning it does not break the flow of text. It is used to highlight code snippets within larger blocks of text.

2. Default Styling: By default, browsers render the text inside the <code> tag in a monospaced (or fixed-width) font. This helps to distinguish code from regular text, as code typically requires a monospaced font for proper alignment.

3. Semantics: The <code> tag does not provide additional semantic meaning beyond indicating that the enclosed text is code. It should be used in conjunction with other HTML elements for code blocks, such as <pre>, to display larger or multiline code snippets.

Example Usage:

<p>To create a function in JavaScript, use the <code>function</code> keyword.</p>

In this example:

• The <code> tag is used to highlight the function keyword, indicating that it is code.

Multiline Code:

For multiline code or blocks of code, the <code> tag is often used within other elements such as <pre> to preserve formatting and indentation.

Example with <pre>:

<pre>
<code>
function sayHello() {
  console.log('Hello, world!');
}
</code>
</pre>

In this example:

• The <pre> tag preserves the formatting and indentation of the code block.
• The <code> tag indicates that the enclosed text is code.

CSS Styling:

You can use CSS to customize the appearance of the <code> tag if needed. For example, you might want to change the font family, color, or background of the code.

Example CSS:

<style>
  code {
    font-family: 'Courier New', monospace; /* Use a monospaced font */
    background-color: #f4f4f4; /* Light grey background */
    padding: 2px 4px; /* Add some padding */
    border-radius: 4px; /* Round the corners */
  }
</style>

Accessibility and SEO:

• Accessibility: The <code> tag helps screen readers and other assistive technologies recognize and differentiate code from regular text, improving accessibility for users who rely on these tools.
• SEO: The <code> tag does not directly impact SEO, but providing clear and well-formatted code examples can improve the usability and quality of content.
