::first-letter CSS pseudo-element selector

CSS pseudo-element that allows styling only the first "letter" of text within an element. Useful for implementing initial caps or drop caps styling.

CSS Initial Letter

Method of creating an enlarged cap, including a drop or raised cap, in a robust way.

CSS initial value

A CSS value that will apply a property's initial value as defined in the CSS specification that defines the property

CSS revert value

A CSS keyword value that resets a property's value to the default specified by the browser in its UA stylesheet, as if the webpage had not included any CSS. For example, `display:revert` on a `<div>` would result in `display:block`. This is in contrast to the `initial` value, which is simply defined on a per-property basis, and for `display` would be `inline`.

CSS unset value

A CSS value that's the same as "inherit" if a property is inherited or "initial" if a property is not inherited.
