The Embedded JavaScript/CSS View tab is accessible when you are creating an HTML page. From here, you can create JavaScript code and Cascading Style Sheets for use in your HTML page. You can reference existing Cascading StyleSheet files and JavaScript files by typing the URL in the URL/Find File area of the Settings panel. You can also search for these files by using the CSS or JavaScript commands.

Embedded code is used only in the host HTML file. External code is available to be used by multiple files.
