You can create all kinds of different elements for the web or for CD-ROMs and devices using Flash. First, you create a file in the Flash authoring tool, which you use to output SWF files. SWF files are the files that you can put online when you embed it in a web page. The Macromedia Flash Player plug-in then displays the SWF file, so your website visitors can view or interact with the content.
Your SWF file can contain video, MP3 sound, animations, images, data, and so forth. The benefit of using an SWF file over other formats is that the Flash Player plug-in is incredibly common. Let's get started building a banner.
Open the Flash application.
By default, Flash displays the Start Page (see Figure 1), which enables you to select a recently edited document, create a new Flash document (or other documents if you use Flash MX Professional), or create a new document using a pre-built template.
Figure 1: By default, Flash displays the Start Page when it is launched. This figure shows the options available in Flash MX Professional.
It's a good idea to save a new document when you start working with it (and often thereafter) so you don't lose any of your hard work. After you finish saving the file, proceed to the following exercise where you will change the document's properties.
