To add the basic styles features to your editor install the @ckeditor/ckeditor5-basic-styles package:
npm install --save @ckeditor/ckeditor5-basic-styles
And add the plugins which you need to your plugin list. Then, simply configure the toolbar items to make the features available in the user interface.
import Bold from '@ckeditor/ckeditor5-basic-styles/src/bold';
import Italic from '@ckeditor/ckeditor5-basic-styles/src/italic';
import Underline from '@ckeditor/ckeditor5-basic-styles/src/underline';
import Strikethrough from '@ckeditor/ckeditor5-basic-styles/src/strikethrough';
import Code from '@ckeditor/ckeditor5-basic-styles/src/code';
import Subscript from '@ckeditor/ckeditor5-basic-styles/src/subscript';
import Superscript from '@ckeditor/ckeditor5-basic-styles/src/superscript';
ClassicEditor
.create( document.querySelector( '#editor' ), {
plugins: [ Bold, Italic, Underline, Strikethrough, Code, Subscript, Superscript ],
image: {
toolbar: [ 'bold', 'italic', 'underline', 'strikethrough', 'code','subscript', 'superscript' ]
}
} )
.then( ... )
.catch( ... );

Each style feature registers a command which can be executed from code. For example, the following snippet will apply the bold style to the current selection in the editor:
editor.execute( 'bold' );
We recommend using the official {@link framework/guides/development-tools#ckeditor-5-inspector instance 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.
The source code of the feature is available on GitHub in https://github.com/ckeditor/ckeditor5-basic-styles.
