🙋 Introduction

In the world of web development, the <pre> tag stands out as a powerful HTML element, especially when it comes to displaying code blocks with precision.

This comprehensive guide will delve into the details of the HTML <pre> tag, exploring its syntax, use cases, and best practices.

🤔 What is <pre> Tag?

The <pre> tag, short for preformatted text, is an HTML element designed to preserve both spaces and line breaks. It is particularly useful when you want to display code blocks or any text where formatting and spacing are crucial.

💡 Syntax

Implementing the <pre> tag is straightforward. Wrap your code or text within the opening <pre> and closing </pre> tags to ensure that the content is rendered exactly as it appears in the HTML source code.

<pre>
  Your Code or Text Here
</pre>

🧰 Attributes

While the <pre> tag itself doesn't have many attributes, you can combine it with the <code> tag for styling and additional customization. This is especially useful when presenting code within a preformatted block.

      return "Hello, World!";
    }
  </code>
</pre>

📚 Common Use Cases

Code Blocks:

The primary purpose of the <pre> tag is to display code blocks without losing formatting. It's commonly used when you want to present code examples in a clear and readable manner.
