Example
javascript``
import React from 'react';
import { Editor, convertToRaw } from 'draft-js';
import { stateToHTML } from 'draft-js-export-html';
import Raw from 'draft-js-raw-content-state';
import createStyles from 'draft-js-custom-styles';
const customStyleMap = {
MARK: {
backgroundColor: 'Yellow',
fontStyle: 'italic',
},
};
// Passing the customStyleMap is optional
const { styles, customStyleFn, exporter } = createStyles(['font-size', 'color', 'text-transform'], 'CUSTOM_', customStyleMap);
class RichEditor extends React.Component {
constructor(props) {
super(props);
this.state = {
editorState: new Raw().addBlock('Hello World', 'header-two').toEditorState(),
readOnly: false,
};
this.updateEditorState = editorState => this.setState({ editorState });
}
toggleFontSize = fontSize => {
const newEditorState = styles.fontSize.toggle(this.state.editorState, fontSize);
return this.updateEditorState(newEditorState);
};
removeFontSize = () => {
const newEditorState = styles.fontSize.remove(this.state.editorState);
return this.updateEditorState(newEditorState);
};
addFontSize = val => () => {
const newEditorState = styles.fontSize.add(this.state.editorState, val);
return this.updateEditorState(newEditorState);
};
toggleColor = color => {

return this.updateEditorState(newEditorState);
};
toggleTextTransform = color => {
const newEditorState = styles.textTransform.toggle(this.state.editorState, color);
return this.updateEditorState(newEditorState);
};
render() {
const { editorState } = this.state;
const inlineStyles = exporter(this.state.editorState);
