How to generate an HTML file from a FrameMaker book? I want to view the book in a Web browser.

You can follow this tutorial to generate an HTML file from a FrameMaker book.

1. Open the FrameMaker book like FM-Book-Example.book, and click "Edit > Update Book" menu to ensure the entire book is updated.

2. Select the FrameMaker book in the book panel on the left. Then click "File > Save Book As" menu You see the "Save Book" screen.

3. Enter the PDF file name like "FM-Book-Example". And make sure that "Save as type" is set to "HTML (*.htm)".

4. Click "Save".

5. Wait for FrameMaker to finish generating the HTML file.

6. Go to the folder where the HTML file was saved. You actually see two files generated:

FM-Book-Example.htm - Contains HTML code for the book
FM-Book-Example.css - Contains display CSS styles 

7. Open FM-Book-Example.htm in a Web Browser. You see that the page layout is removed. But text formatting attributes are maintained.

8. Open the HTML file in a text editor. You see how the book content is organized.
