When you publish a Flash movie, you can choose to publish it at a fixed size (the same as the movie dimensions, or another size), or at some percent of the screen, with different options that determine what cropping and stretching will happen to make the content fit the user's browser window. The most common publish option for movies containing bitmap images, as our sample movie does, is as a fixed size movie, the same size as the stage dimensions. This is also the default if no changes are made in the Flash tab of the Publish Settings dialog box. Once the movie has been published, producing both a swf and an html file, the html file can be opened in Dreamweaver or another HTML editor and altered. Below are some examples:
If you publish a movie with the default Publish settings, you'll get a swf and an html page that embeds that swf and displays it in the upper left corner of the browser window, at a size equal to the stage size of the movie. Because no margin or other formatting tags are included in the html, there will be a small margin at the top and left of the swf content in Mozilla-based browsers, which assign a default margin.
