The #1 WYSIWYG Editor updated with new features, redesigned UI.

Browser Compatibility:

safari firefox ie chrome opera mozilla netscape

Rich Text Editor control will automatically determine the browser that has requested the page and render the appropriate solution for that browser. However, some control features cannot be rendered on older browsers.

Uplevel Browsers

Browsers are split into two distinctive groups: "uplevel" (newer versions) and "downlevel" (earlier versions). Uplevel browsers are defined as Edge Browser, IE 11, all Internet Explorer versions from 6.0 up on Windows, Firefox 2.0+, Chrome, Mozilla 1.3+, Netscape 7+, Opera 9.x and Safari (1.3+). This includes Macintosh and Linux. Rich Text Editor will render rich UI in uplevel browsers.

Rich Text Editor is pure JavaScript and HTML in the browser, it requires no browser plug-ins, ActiveX controls or Java Applets.
