As you dive into the world of web development, understanding how to correctly use characters in HTML is crucial. This article serves as a comprehensive guide to HTML Entities, which are special codes that allow you to include characters that have special meanings in HTML or that may not be easily typeable on a keyboard.
I. What Are HTML Entities?
A. Definition
HTML Entities are special codes used in HTML to represent characters that either have reserved meanings (like < and >) or are not readily available on your keyboard. These entities begin with an ampersand (&) and end with a semicolon (;).
B. Purpose of HTML Entities
The main purpose of HTML entities is to allow you to display special characters in web content. For instance, without entities, a less-than sign (<) would be interpreted as the beginning of a tag, causing errors or incorrect display of content.
II. Why Use HTML Entities?
A. Avoiding Parsing Issues
Using HTML entities helps you avoid parsing issues with browsers. For example, if you want to display an HTML element like <div>, you would need to use that entity rather than the actual angle brackets.
B. Representing Special Characters
Entities allow you to represent special characters such as ©, ™, or even characters from different languages that may not be part of the basic ASCII set.
