The {@link module:alignment/alignment~Alignment} feature enables support for text alignment. You can use it to align your content to left, right and center or to justify it.

## Related features
There are more CKEditor 5 features that can help you organize your content:
* {@link features/title Document title} – Clearly divide your content into a title and body.
* {@link features/headings Headings} – Split your content into logical sections.
* {@link features/indent Block indentation} – Organize your content into visually separated blocks, indent crucial paragraphs, etc.
* {@link features/block-quote Block quote} – Include block quotations or pull quotes in the rich-text content.
* {@link features/remove-format Remove format} – Easily clean basic text formatting.
## Configuring alignment options
It is possible to configure which alignment options are available in the editor by setting the {@link module:alignment/alignment~AlignmentConfig#options `alignment.options`} configuration option. You can choose from `'left'`, `'right'`, `'center'` and `'justify'`.
Note that the `'left'` option should always be included for the LTR content. Similarly, the `'right'` option should always be included for the RTL content. Learn more about {@link features/ui-language#setting-the-language-of-the-content configuring language of the editor content}.
For example, the following editor will support only two alignment options: to the left and to the right:
```js
ClassicEditor
.create( document.querySelector( '#editor' ), {
alignment: {
options: [ 'left', 'right' ]
},
toolbar: [
'heading', '|', 'bulletedList', 'numberedList', 'alignment', 'undo', 'redo'
]
} )
.then( ... )
.catch( ... );
```

## Configuring the toolbar
You can choose to use the alignment dropdown (`'alignment'`) or configure the toolbar to use separate buttons for each of the options:
```js
ClassicEditor
.create( document.querySelector( '#editor' ), {
toolbar: [
'heading', '|', 'alignment:left', 'alignment:right', 'alignment:center', 'alignment:justify'
]
} )
.then( ... )
.catch( ... );
```

## Common API
The {@link module:alignment/alignment~Alignment} plugin registers:
* Dropdown: `'alignment'`.
* Buttons: `'alignment:left'`, `'alignment:right'`, `'alignment:center'`, `'alignment:justify'`.
The number of options and their names are based on the {@link module:alignment/alignment~AlignmentConfig#options `alignment.options`} configuration option).
* Command: `'alignment'`:
You can align the currently selected block(s) by executing one of these commands:
```js
editor.execute( 'alignment', { value: 'center' } );
```
We recommend using the official {@link framework/guides/development-tools#ckeditor-5-inspector CKEditor 5 inspector} for development and debugging. It will give you tons of useful information about the state of the editor such as internal data structures, selection, commands, and many more.
