AlignmentFormat

Available alignment options.

The available options are: 'left', 'right', 'center' and 'justify'. Other values are ignored.

Note: It is recommended to always use 'left' or 'right' as these are default values which the user should normally be able to choose depending on the language of the editor content.

ClassicEditor
  .create( editorElement, {
    alignment: {
      options: [ 'left', 'right' ]
    }
  } )
  .then( ... )
  .catch( ... );

By default the alignment is set inline using the text-align CSS property. To further customize the alignment, you can provide names of classes for each alignment option using the className property.

Note: Once you define the className property for one option, you need to specify it for all other options.

ClassicEditor
  .create( editorElement, {
    alignment: {
      options: [
        { name: 'left', className: 'my-align-left' },
        { name: 'right', className: 'my-align-right' }
      ]
    }
  } )
  .then( ... )
  .catch( ... );
