Styling in EJ2 TypeScript Rich text editor control

25 Jul 202421 minutes to read

Font name and size

By default, the Rich Text Editor initializes with the font name and font size set to “Default.” This configuration means that the editor will inherit the font family and font size from its parent element in the application. If the content in the Rich Text Editor inherits its font properties from any parent element, these inherited values will appear as the default selections in the respective drop-down menus.

Customizing font styles for text sections

To apply a different font style to a specific section of the content:

  1. Select the text that you want to customize.
  2. In the editor’s toolbar, open the font name drop-down menu.
  3. Choose the desired font style to apply it to the selected text.
  4. Similarly, you can change the font size by selecting the desired size from the font size drop-down menu.

This will update the font style and size for the highlighted section of text, allowing customization within the content of the Rich Text Editor.

FontName DropDowns

The following table lists the default font name and width of the fontname dropdown and the available list of font names.

Default Key Default Value
default null
width 72px
items { text: ‘Default’, value: ‘’ },{ text: ‘Segoe UI’, value: ‘Segoe UI’ },{ text: ‘Arial’, value: ‘Arial,Helvetica,sans-serif’ },{ text: ‘Courier New’, value: ‘Courier New,Courier,monospace’ },{ text: ‘Georgia’, value: ‘Georgia,serif’ },{ text: ‘Impact’, value: ‘Impact,Charcoal,sans-serif’ },{ text: ‘Lucida Console’, value: ‘Lucida Console,Monaco,monospace’ },{ text: ‘Tahoma’, value: ‘Tahoma,Geneva,sans-serif’ },{ text: ‘Times New Roman’, value: ‘Times New Roman,Times,serif’ },{ text: ‘Trebuchet MS’, value: ‘Trebuchet MS,Helvetica,sans-serif’ },{ text: ‘Verdana’, value: ‘Verdana,Geneva,sans-serif’ }

FontSize DropDowns

The following table lists the default font size and width of the fontsize dropdown and the available list of font sizes.

Default Key Default Value
default null
width 60px.
items { text: ‘Default’, value: ‘’ },{ text: ‘8’, value: ‘8pt’ },{ text: ‘10’, value: ‘10pt’ },{ text: ‘12’, value: ‘12pt’ },{ text: ‘14’, value: ‘14pt’ },{ text: ‘18’, value: ‘18pt’ },{ text: ‘24’, value: ‘24pt’ },{ text: ‘36’, value: ‘36pt’ }.

The following sample demonstrates the option to add the font name and font size tools to the toolbar as well as modify the default width of the tools.

import { enableRipple } from '@syncfusion/ej2-base';
enableRipple(true);
/**
 * Rich Text Editor default sample
 */
import { RichTextEditor, Toolbar, Link, Image, HtmlEditor, QuickToolbar } from '@syncfusion/ej2-richtexteditor';
RichTextEditor.Inject(Toolbar, Link, Image, HtmlEditor, QuickToolbar);


let defaultRTE: RichTextEditor = new RichTextEditor({
  height: 340,
  toolbarSettings: {
        items: [ 'FontName', 'FontSize']
    },
    fontSize: {
        width: '40px'
    },
    fontFamily: {
        width: '60px'
    }
});
defaultRTE.appendTo('#defaultRTE');

Custom font and size

The Rich Text Editor provides custom fonts and sizes with the existing list. If you want to add additional font names and font sizes to font drop-down, pass the font information as JSON data to the items field of fontsize and fontFamily property.

import { enableRipple } from '@syncfusion/ej2-base';
enableRipple(true);
/**
 * Rich Text Editor default sample
 */
import { RichTextEditor, Toolbar, Image,  Link, HtmlEditor, QuickToolbar, NodeSelection } from '@syncfusion/ej2-richtexteditor';
RichTextEditor.Inject(Toolbar, Image,  Link, HtmlEditor, QuickToolbar );

let defaultRTE: RichTextEditor = new RichTextEditor({
    height: 340,
    toolbarSettings: {
        items: [ 'FontName', 'FontSize']
    },
    fontSize: {
        default: '10 pt',
        width: '40px',
        items: [{ text: '8 pt', value: '8pt' },
        { text: '10 pt', value: '10pt' },
        { text: '12 pt', value: '12pt' },
        { text: '14 pt', value: '14pt' },
        { text: '42 pt', value: '42pt' }]
    },
    fontFamily: {
        default: 'Segoe UI',
        width: '60px',
        items: [
        { text: 'Segoe UI', value: 'Segoe UI' },
        { text: 'Arial', value: 'Arial,Helvetica,sans-serif' },
        { text: 'Courier New', value: 'Courier New,Courier,monospace' },
        { text: 'Georgia', value: 'Georgia,serif' },
        { text: 'Impact', value: 'Impact,Charcoal,sans-serif' },
        { text: 'Calibri Light', value: 'CalibriLight' }]
    }
});
defaultRTE.appendTo('#defaultRTE');

Font and background color

To apply font color or background color for a selected content of Rich Text Editor, use font color and background color tools.

The Rich Text Editor provides customs font color and background color with the existing list through the colorCode field of fontColor and backgroundColor.

The FontColor and BackgroundColor property has two modes: Picker and Palette. Palette mode has a predefined set of colorCodes, and in the picker mode, more colors are provided. Through the modeSwitcher, you can switch between these two options.

import { enableRipple } from '@syncfusion/ej2-base';
enableRipple(true);

import { RichTextEditor, Toolbar, Link, Image, HtmlEditor, QuickToolbar } from '@syncfusion/ej2-richtexteditor';
RichTextEditor.Inject(Toolbar, Link, Image, HtmlEditor, QuickToolbar);

let defaultRTE: RichTextEditor = new RichTextEditor({
  height: 340,
  toolbarSettings: {
    items: [ 'FontColor', 'BackgroundColor']
  },
  backgroundColor: {
      modeSwitcher : true
  },
  fontColor: {
      modeSwitcher : true
  }
});
defaultRTE.appendTo('#defaultRTE');

Editor content styles

By default, the content styles of the Rich Text Editor are not returned when retrieving HTML value from the editor. So, the styles are not applied when using HTML values outside of the editor. To get the styles to the Rich Text Editor’s content for your application, copy and use the styles listed below directly in your application. They are used in the UI elements of the Rich Text Editor.

Make sure to add a CSS class ‘e-rte-content’ to the content container.


.e-rte-content p {
  margin: 0 0 10px;
  margin-bottom: 10px;
}

.e-rte-content li {
