Some notes about entities
<p>learning is fun</p>
An entity is a set of characters used to represent a reserved character in HTML
These types of character references are known as named character references. Named references start with an ampersand sign (&) and end with a semicolon (;). By using a named character reference, the HTML parser will not confuse this with an actual HTML element.
Another type of character reference would be the decimal numeric reference. This character reference starts with an ampersand sign and hash symbol (#), followed by one or more decimal digits, followed by a semicolon.
The last type of character reference would be the hexadecimal numeric reference. This character reference starts with an ampersand sign, hash symbol, and the letter x. Then it is followed by one or more ASCII hex digits and ends with a semicolon.
