Most graphics programs can create transparent GIF images, in which one color is designated as transparent When the image displays on your page, the background color of the page shows through the transparent area You can also create sophisticated designs by stacking images of different transparency levels on top of each other (Imagine a stack of plastic overhead transparencies, each containing a different image) Stackable images whether transparent or opaque are referred to as layers in most graphics programs The procedures for setting the transparent color are similar in most graphics programs Follow these steps to set transparent color in Paint Shop Pro, a trial version of which is included on the companion CD: Code128 Creator In Visual Basic .NET Using Barcode creator for .NET Control to generate, create Code-128 image in VS .NET applications. 1 Open the image you want to make transparent 2 Choose Layers Properties

You can insert a sound file on a Web page in one of two ways: as a link or as an embedded sound The following sections show you how to use the HTML tags necessary for each method You can also insert a sound as a part of the page s background so that the sound plays automatically whenever the page displays Flip to the section Creating a background sound, later in this chapter, for more information To find out how to create sound files to include in your Web pages, check out Book V Painting Code 39 Full ASCII In .NET Framework Using Barcode maker for .NET Control to generate, create Code 3 of 9 image in .NET framework applications. Inserting a link to a sound file
Not everyone likes sound to play automatically The advantage of linking to a sound file is that it gives your visitors a choice The sound file isn t downloaded to the user s computer until the user clicks the sound file link To insert a link to a sound file, follow these steps: 1 Obtain a sound file you want linked to your Web site 2 Place the sound file in the same directory as the HTML document that will contain the link
3 Add an <A> tag, some descriptive text, and an </A> tag to the HTML
file as follows: <A HREF= soundwav >Click here to play the sound</A>
Be sure to type the name of your sound file in the HREF attribute
Incorporating Video Clips
Embedding a sound file
Embedding a sound file displays sound controls (stop, play, and start) on a Web page, allowing visitors to control when and how the sound file plays You can embed a sound on a Web page by using an <EMBED> tag as follows: <EMBED SRC= soundwav >
The SRC attribute specifies the name of the sound file Be sure to specify a fully qualified filename (one that includes the full path to the file) if your sound file is located in a different directory than your HTML file For example: SRC= d:\mysite\mysounds\soundwav Creating a background sound
A background sound plays automatically whenever a user displays your Web page To add a background sound to a page, follow these steps: 1 Obtain a sound file you want to use as a background sound 2 Place the sound file in the same directory as the HTML file 3 Add a <BGSOUND> tag following the document s <BODY> tag Use the
