React Html Editor - Overview
The HtmlEditor component is a client-side WYSIWYG text editor. The editor allows users to format text and integrate media elements into documents. The result can be exported to HTML.
Users can edit and customize content using the toolbar that can contain predefined and custom controls. To specify the available controls, use the items array. In this demo, the toolbar contains predefined controls.
DevExtreme Accessibility Compliance
DevExtreme component libraries meet a variety of WCAG and Section 508 compliance standards. To assess this demo’s accessibility level, click the Run AXE® Validation button to launch the AXE® web accessibility evaluation tool.

The overall accessibility level of your application depends on the HtmlEditor features used.
To give you the ability to edit code on the fly, the demo uses SystemJS. For this reason, launching the demo takes some time. We strongly recommend that you do not use this approach in real projects.
