It is easy to use HTML Instant. Just enter a rich text in the left WYSIWYG pane, or code in the right pane. The formatted text and HTML will keep automatically in sync. You can use the icons on the top for formatting, such a font size, underline, paragraphs, etc or create such formating manually entering paricular HTML constructs.
