<p>This article lets us learn how to define HTML entities to display special characters on the browser, and they are case sensitive. HTML Entities are also termed as Character entity references which help to include various 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 interprets automatically (understood that they are mark-up language). Html entities’ main benefits are easy to use, and remember, it replaces the characters that are not on the keyboard. Here we will discuss different types of entities and basic examples to illustrate the functionality.</p>
<h3 id="Syntax-for-HTML-Entities">Syntax for HTML Entities</h3>
<p>HTML entities give different varieties of characters, assigning icons, mathematical operators, and even geometric complex shapes.</p>
<p><strong>Representation:</strong> 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.</p>
<p><strong><b>Syntax:</b></strong></p>
<p><b></b><strong><b>1. Using a Character Entity</b></strong></p>
<pre class="brush:php;toolbar:false">& [Entity name character];</pre>
<p><strong>2. Using Number</strong></p>
<pre class="brush:php;toolbar:false">&#Entity no;</pre>
<p><strong>Explanation:</strong> The 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 that is 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).</p>

<h3 id="Conclusion">Conclusion</h3>
<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. Our system keyboard supports some technical and currency symbols using these symbols to display on the HTML page.</p>
