Emojis are characters from the UTF-8 character set: 😄 😍 💗
What are Emojis?
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.
The HTML charset Attribute
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">
If not specified, UTF-8 is the default character set in HTML.
UTF-8 Characters
Many UTF-8 characters cannot be typed on a keyboard, but they can always be displayed using numbers (called entity numbers):
A is 65
B is 66
C is 67
Example
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
</head>
<body>
<p>I will display A B C</p>
<p>I will display A B C</p>
</body>
</html>
Example Explained
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).

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">

- <html>
- <head>
- <meta charset="UTF-8">
- </head>
- <body>
- <h1>Sized Emojis</h1>
