HTML symbols are characters that cannot be found on a standard keyboard and are used in the markup to represent or add special characters to the text content. These symbols can be added using HTML entities, which are a combination of characters that start with an ampersand (&) and end with a semicolon (;). There are different types of entities for different purposes, such as mathematical symbols, Greek letters, and various icons¹.

Example: Euro Symbol

To display the euro symbol, you can use the entity name €, the decimal code €, or the hexadecimal code €¹.

Mathematical Symbols

HTML supports a variety of mathematical symbols. For instance, to represent the "for all" symbol, you can use ∀, ∀, or ∀¹.

Greek Letters

Greek letters are often used in scientific and mathematical contexts. To add a Greek alpha symbol, you can use α, α, or α¹.
