Emojis look like images, or icons, but they are not.
They are letters (characters) from the UTF-8 (Unicode) character set.
UTF-8 covers almost all of the characters and symbols in the world.
Emojis are characters from the UTF-8 character set: 😂
To display an HTML page correctly, a web browser must know the character set used in the page.
This is specified in the <meta>
tag:
<meta charset="UTF-8">
Many UTF-8 characters cannot be typed on a keyboard, but they can always be displayed using numbers (called entity numbers):
Example:
HTML
<!DOCTYPE html>
<html>
<meta charset="UTF-8">
<body>
<p>I will display A B C</p>
<p>I will display A B C</p>
</body>
</html>
The <meta charset="UTF-8">
element defines the character set.
The characters A, B, and C, are displayed by the numbers 65, 66, and 67.
To let the browser understand that you are displaying a character, you must start the entity number with &# and end it with ; (semicolon).
Emojis are also characters from the UTF-8 alphabet:
Example:
HTML
<!DOCTYPE html>
<html>
<meta charset="UTF-8">
<body>
<h1>My First Emoji</h1>
<p>😀</p>
</body>
</html>
Example:
HTML
<!DOCTYPE html>
<html>
<meta charset="UTF-8">
<body>
<h1>Sized Emojis</h1>
<p style="font-size:48px">
😀 😄 😍 💗
</p>
</body>
</html>
