### 18.5 Creating pop-ups for HTML Help

HTML Help supports only text pop-ups. By itself, HTML Help does not allow any font changes in pop-ups, not even bold or italics; nor any images; nor any HTML code. To include these features in an HTML Help pop-up, you need a third-party plug-in or program, such as WinHelp.
