What’s Microsoft Silverlight?
According to Microsoft at http://silverlight.net, Silverlight is a plug-in for delivering media experi-
ences and rich interactive applications for the Web. Microsoft Expression Blend is an applica-
tion that creates interactive media for display by the Silverlight plug-in.
Adding a Flash Animation to a Web Page
You’ve seen some examples of Flash and are aware of issues related to Flash and Web
usability. Now let’s take a look at the XHTML that is needed to use Flash media on a
Web page.
Previously, both the tag and the non-standard tag were needed to
reliably display Flash media on Web pages. Today’s modern browsers support the


tag.
The tag specifies the beginning of Flash media on a Web page. Its closing
tag, , specifies the ending of Flash media. As previously discussed, the
tag is a multipurpose tag for adding various types of objects to a Web page.
The tag’s attributes vary, depending on the type of object being referenced.
The minimum attributes required when working with Flash media are described in
Table 11.3.
Table 11.3Minimal Flash media attributes

Attribute Description and Value
accesskey Optional; Specifies a hotkey for keyboard access, Windows users press the hotkey and the ∏key
at the same time.
type The MIME type of the object, use type="application/x-shockwave-flash"
data File name of the Flash media (.swf file)
height Specifies the height of the object area in pixels
tabindex Optional; A numeric value that specifies the tabbing order of the Flash media
title Optional; Specifies a brief text description that may be displayed by browsers or assistive technologies
width Specifies the width of the object area in pixels
(MSAA). This makes Flash content available to visitors using assistive technology such
as the GW Micro Window-Eyes or Freedom Scientific JAWS screen reader. Expect more
improvements in Flash and accessibility as Adobe continues to focus on this area.
Today’s Web developer needs to know how to add a Flash .swf file to a Web page. If
you are working on a large project, a graphic designer may create the effect and pass it
to you for placement on a page. If you are working on a small project, you may be
expected to create Flash .swf files yourself. Adobe offers a free trial download of the
Flash application, including a few tutorials and lessons on using Flash.
