To include the infinity symbol in an HTML document, use:

HTML entity: ∞
Unicode decimal equivalent: ∞

Just copy and paste one of the above directly into your HTML at the required location.

Inserting into HTML elements

The infinity symbol can be utilized within various HTML elements to enhance content like:

<h2>My love for coding is &infin;</h2>
<p>Number of bugs fixed: &#8734;</p> <!-- Self-deprecating dev humor -->
<img src="race_track.jpg" alt="Race track shaped like &infin;">

These examples demonstrate the versatility of HTML when dealing with symbolic characters.

Guaranteeing UTF-8 encoding

For proper display of the infinity symbol and other Unicode characters, it's crucial to use UTF-8 encoding. Include the following line in the <head> tag of your HTML:

<meta charset="UTF-8">

Doing so ensures the correct rendering of the symbol across all browser platforms.

Choosing the correct font

Although all fonts should render the infinity symbol, some may display it more clearly than others.

<!-- The Infinity Gauntlet of Fonts -->
<p style="font-family: Arial;">&infin;</p>
<p style="font-family: Verdana;">&infin;</p>
<p style="font-family: Times New Roman;">&infin;</p>

Check that your chosen font presents the symbol to your satisfaction, or pick a web-safe font known for its glyph coverage.

Styling HD Infinity with CSS

Complement HTML entities with CSS to stylize the infinity symbol, giving it the HD rendering it deserves:

<span class="HD-infinity-symbol">&infin;</span>

.HD-infinity-symbol {
  font-size: 5em;                       // Bigger the better
  color: #FF5733;                       // Hot as an eternal flame
  text-shadow: 2px 2px 4px #000000;     // Shadows are cool, but not on your future!
}

This snippet gives a quick look into the universe of possibilities when using CSS with HTML entities.
