ampersand (&)

Don't use & in place of and in text or headings unless you're referring to the use of the symbol in UI.

It's OK to use & in content for technical audiences that covers its use in HTML or programming languages.

Example
To display a reserved character in HTML, use a character reference, which consists of an ampersand, the code name or number of the character, and a semicolon. For example, use &lt; or &#60; to display the less than sign (<), and use &gt; or &#62; to display the greater than sign (>).
