Inserting An HTML Snippet
This topic is for slightly more advanced users, but the general idea is simple. Suppose you have and HTML code snippet from a website such as YouTube, Flickr, or other source, and you need to embed it into your page. We'll show you how to do that.
First, open a new page, or an existing page in the authoring panel for editing. Next, click on the HTML editor button. This button is outlined in red below.
Next, enter the snippet you were provided into the textbox that pops up, and click "Update."
Once this is done, and you publish your web page, your embedded object should be visible publicly. It will not, however, be immediately visible in the editor after you click "Update."
