These instructions will help you modify the HTML of content on your website or insert new HTML. While editing the website, select the HTML button.
A popup will appear, showing you the HTML of the content you've already placed on the page. If you are pasting pure HTML you've retrieved from another website (Facebook button, iFrame, etc), paste it in this text box. For beginners it is recommended that you paste the code at the very beginning, and then drag the object into place using the visual editor.
More advanced users may find it easier to paste the code in the appropriate place using the HTML editor.
Some limitations still exist. For example, window.onload will not work inside an HTML Box.
