An **HTML entity** is used to display invisible characters and reserved characters that would otherwise be interpreted as HTML code. It is a piece of text, or string, that begins with an ampersand (`&`) and ends with a semicolon (`;`).

Typically, HTML will interpret the less-than sign (`<`) as a tag. If you would like to have the less-than sign as text, HTML allows you to write `&lt;`, as seen from the example above.

# When to use HTML entities?

Generally, you don't need to use HTML entities if your editor supports Unicode. For some instances, entities can be useful:

- Your editor does not support Unicode.

- Your keyboard does not support the character you would like to type, such as em-dash or the copyright symbol.

- You want specific HTML-specific characters like `<`, `&`, or `"`.
