Kebab case

Kebab case is a way of writing phrases without spaces, where spaces are replaced with hyphens -, and the words are typically all lower case. The name comes from the similarity of the words to meat on a kebab skewer. It's often stylized as "kebab-case" to remind the reader of its appearance.

Kebab casing is often used as a variable naming convention. However, in many languages, hyphens represent subtraction, so kebab casing is not an option. CSS properties such as background-color and font-family are in kebab case, and so are HTML attributes such as aria-label and data-*.

Kebab-cased words are often simply referred to as hyphenated.
