Welcome to the world of web development! One of the fundamental aspects of creating web pages is understanding how to represent special characters properly. In this article, we will delve into HTML Character Entities, essential tools that help us display characters that might otherwise be misinterpreted by the browser.

I. Introduction

A. Definition of HTML Character Entities

HTML Character Entities are a type of code used in HTML to represent characters that have specific meanings in HTML syntax or characters that are not easily typed on a keyboard. Instead of typing the character directly, we use a unique code that the browser interprets correctly.

B. Importance of Using Character Entities in HTML

Using character entities is crucial to ensure that the characters you want to display on your web page appear correctly. It prevents unintended formatting issues and allows for the inclusion of special symbols in your content.

II. What are Character Entities?

A. Explanation of Character Entities

A character entity begins with an ampersand (&) and ends with a semicolon (;). Between these two characters, we place a code that represents the desired character. For example, the less-than symbol (<) can be represented as <.

B. Usage in HTML Code

Character entities can be used anywhere in HTML code where you want to insert special characters. They are particularly useful for:

• Including symbols in the text
• Preventing HTML syntax errors
• Enhancing the readability of certain content types
