HTMLfailid

HTMLfailid, also known as HTML entities, are special codes used in HTML (HyperText Markup Language) to represent characters that are reserved in HTML or have special meanings. These entities are used to ensure that web browsers correctly interpret and display text. HTML entities begin with an ampersand (&) and end with a semicolon (;), with the specific code in between.

There are several types of HTML entities:

1. Named entities: These use descriptive names to represent characters. For example, the less-than symbol (<) is represented as &lt; and the greater-than symbol (>) is represented as &gt;.

2. Numeric character references: These use decimal or hexadecimal numbers to represent characters. For example, the copyright symbol (©) can be represented as &#169; (decimal) or &#xA9; (hexadecimal).

3. Predefined entities: These are a set of commonly used entities that are predefined in HTML. Examples include &amp; for the ampersand (&), &quot; for the double quotation mark ("), and &apos; for the single quotation mark (').

HTML entities are particularly useful when including special characters in HTML documents, such as those with reserved meanings or those that are not easily typed on a standard keyboard. They help ensure that the text is displayed correctly across different web browsers and platforms.
