HTML Entities: Displaying Special Characters in Web Pages

HTML entities are special codes used to represent characters that have special meaning in HTML or are difficult to type directly. They play a crucial role in ensuring proper rendering and maintaining the integrity of web content.

Why Use HTML Entities?

HTML entities serve several important purposes:

• Displaying reserved characters (like < and >) without interpreting them as HTML code
• Representing characters not easily typed on a standard keyboard
• Ensuring consistent rendering across different browsers and devices
• Improving accessibility for screen readers and other assistive technologies

Syntax and Usage

HTML entities can be written in two formats:

1. Named entities: &entityname;
2. Numeric entities: &#entitynumber; or &#xhexnumber;

Common HTML Entities

Character	Entity Name	Entity Number
<	&lt;	&#60;
>	&gt;	&#62;
&	&amp;	&#38;
"	&quot;	&#34;
'	&apos;	&#39;

Examples of HTML Entities in Action

Here are two examples demonstrating the use of HTML entities:

Example 1: Using entities for reserved characters

<p>To create a paragraph in HTML, use the &lt;p&gt; tag.</p>

Output: To create a paragraph in HTML, use the <p> tag.

Example 2: Displaying special characters

<p>The copyright symbol: &copy; 2023</p>
<p>The euro symbol: &euro; 100</p>

Output:

The copyright symbol: © 2023

The euro symbol: € 100

• Always use entities for characters that have special meaning in HTML, such as <, >, and &
• Prefer named entities over numeric entities for better readability when possible
