Introduction to HTML Entities
In this article lets us learn how to define HTML entities to display special characters on the browser and they are case sensitive too. HTML Entities are also termed as Character entity references which help to include a variety of characters to an HTML document like all the symbols are declared as entities followed by ampersand symbol (&). Well-Used characters or reserved characters in HTML tag is lesser / greater than symbol (<,>) when a browser identifies this character it does an interpretation automatically (understood that they are mark-up language). The main benefits of Html entities are easy to use and remember also it replaces the characters which are not in the keyboard. Here we will discuss different types of entities and basic examples to illustrate the functionality.
Syntax for HTML Entities
HTML entities give different varieties of characters which helps to assign icons, mathematical operators and even geometric complex shapes.
Representation: HTML entities are declared using an ampersand (&) with (#) pound character and finally ended with a semicolon; These three elements are very important to avoid complications.
1. Using a Character Entity
& [Entity name character];
2. Using Number
Explanation: Name is easy to remember than the number. Not all the browsers are compatible with the reserved names but the entity numbers are good on browsers. The browsers which do not supports this symbol are displayed as boxes. Html Entities are widely used in the area like a different foreign language (European Language), Punctuation elements, Greek characters, and mathematical Symbols lastly for shapes and arrows. Entity code is much important to avoid a strange error which in some case difficult to pinpoint. HTML entities organize followed by the lists like letters/Symbols with Accents using Unicode, Phonetics Foreign Characters, Currency, Other symbols like smart quotes (These are with straight long dashes).

In the following sections, we shall have a look at Entities on Html Document and the output we see in the browsers.
Examples of HTML Entities
Following are the different examples of HTML entities.
Example #1 – Non-Breaking Space
Additional space between the words is given by using Non- Breaking entities. Following is an implementation of Non-Breaking space between the sentence. A single wide space is included.
<title> Non-Breaking Space Example</title>
<h3>Non-Breaking Space Example</h3>
<p> <p> <b>Life is So Beautiful, must enjoy
To the peak!</b></p></p>
Example #2 – Includes Quotes in a LineOutput
<title>HTML Entities Demo</title>
<div id = "John " & Harry ">
Example #3 – Using the Trademark symbol with CSS Style
font-family: verdana, Helvetica;
<h3> Registered Trademark Symbol: </h3> <h3>HTML Entities demo: </h3> <p>®</p> <p>®</p> <p> This Registered Trademark is a Script used in HTML document. </p>

To the end, we understood the meaning of special characters implemented in the Html document. In some situations, web pages are in need of these special symbols. All these Entities can be used on a website to display the characters. As our system keyboard does support some technical and currency symbols making use of these symbols to display on the HTML page.
