This class is a central building block of tiptap. It does most of the heavy lifting of creating a working [ProseMirror](https://ProseMirror.net/) editor such as creating the [`EditorView`](https://ProseMirror.net/docs/ref/#view.EditorView), setting the initial [`EditorState`](https://ProseMirror.net/docs/ref/#state.Editor_State) and so on.
| `'start'` | Sets the focus to the beginning of the document. |
| `'end'` | Sets the focus to the end of the document. |
| number | Sets the focus to a specific position in the document. |
| `true` | Enables autofocus. |
| `false` | Disables autofocus. |
| `null` | Disables autofocus. |
### Inject CSS
By default, tiptap injects [a little bit of CSS](https://github.com/ueberdosis/tiptap-next/tree/main/packages/core/src/style.ts). With `injectCSS` you can disable that.
```js
import { Editor } from '@tiptap/core'
import { defaultExtensions } from '@tiptap/starter-kit'
| `autofocus` | `Boolean` | `false` | Focus the editor on init. |
| `content` | `Object|String` | `null` | The editor state object used by Prosemirror. You can also pass HTML to the `content` slot. When used both, the `content` slot will be ignored. |
| `editable` | `Boolean` | `true` | When set to `false` the editor is read-only. |
| ~~`editorProps`~~ | ~~`Object`~~ | ~~`{}`~~ | ~~A list of [Prosemirror editorProps](https://prosemirror.net/docs/ref/#view.EditorProps).~~ |
| `element` | `Element` | `false` | Focus the editor on init. |
| `extensions` | `Array` | `[]` | A list of extensions you would like to use. Can be [`Nodes`](/api/nodes), [`Marks`](/api/marks) or [`Extensions`](/api/extensions). |
| `injectCSS` | `Boolean` | `true` | When set to `false` tiptap won’t load [the default ProseMirror CSS](https://github.com/ueberdosis/tiptap-next/tree/main/packages/core/src/style.ts). |
| ~~`parseOptions`~~ | ~~`Object`~~ | ~~`{}`~~ | ~~A list of [Prosemirror parseOptions](https://prosemirror.net/docs/ref/#model.ParseOptions).~~ | -->
## List of available methods
An editor instance will provide the following public methods. They’ll help you to work with the editor.
Don’t confuse methods with [commands](/api/commands), which are used to change the state of editor (content, selection, and so on) and only return `true` or `false`.
| `isActive()` | `name` Name of the node or mark<br>`attrs` Attributes of the node or mark | Returns if the currently selected node or mark is active. |
| `isEditable()` | - | Returns whether the editor is editable. |
| `isEmpty()` | - | Check if there is no content. |
| `registerCommand()` | `name` The name of your command<br>`callback` The method of your command | Register a command. |
| `registerCommands()` | `commands` A list of commands | Register a list of commands. |
| `registerPlugin()` | `plugin` A ProseMirror plugin<br>`handlePlugins` Control how to merge the plugin into the existing plugins. | Register a ProseMirror plugin. |
| `setOptions()` | `options` A list of options | Update editor options. |
| `unregisterPlugin()` | `name` The plugins name | Unregister a ProseMirror plugin. |
