# `MishkaCmsCore.Builder.Actions.ClassVerb`
[🔗](https://github.com/mishka-group/mishka_cms_core/blob/v0.0.1/lib/mishka_cms_core/builder/actions/class_verb.ex#L5)

Toggle, add or remove a class — the three actions that compose with the element's own CSS.

The class lands on the element the click points at, which is the same handle
`MishkaCmsCore.Runtime.PageBuilder.ElementCss` keys a rule on. One identity, two features: toggle
`is-open` here and write `&.is-open { … }` in the CSS box, and that is an accordion with no code in
it.

All three are client actions: `Phoenix.LiveView.JS` moves the class in the browser with no round
trip, and the command survives a patch because it is part of what the server rendered.

# `descriptors`

```elixir
@spec descriptors() :: [map()]
```

The three descriptors this module answers for.
