Embedded object

is any media clip, file, program, or other object that can be run or viewed from within the Web page.

EMBEDDDING A MEDIA CLIP

To embed a sound or video clip on your Web Page, use the following HTML tags:

Where URL is the name of the sound or video file to be embedded, and the WIDTH and the HEIGHT properties define the size of the embedded object on your Web page.

To start the media clip automatically when the page loads, use the following property within the tag:

AUTOSTART = true

EXAMPLES:

CREATING A BACKGROUND SOUND

To create a background sound ( a sound that is played automatically when the browser opens the Web page), use the following tag for Internet Explorer:

Where URL is the filename or location of the sound file, and the LOOP parameter determines how may times the sound file should be played. Loop can be either a digit or INFINITE.

EXAMPLE:

CREATING A BACKGROUND SOUND

To create a background sound for Netscape Navigator or Communicator, use the HTML tag:

EXAMPLE:

SUPPORTING BROWSERS THAT DO NOT RECOGNIZE EMBEDDED OBJECTS

To support browsers that dont recognize the tag use the tag with the following syntax:

HTML tags recognized by older browsers

Where the text and tags placed between the and tags will be rendered by older browsers and ignored by browsers that recognize the tag.

TIPS FOR USING MULTIMEDIA IN YOUR WEB PAGE

Avoid embedding large files on your Web page if the page will be accessed by users with slow Internet connections. Use hyperlinks instead.

Always indicate the size of the media clip when creating a hyperlink to it, so that your users know how large the file is before committing to retrieving it.

Provide different media formats to your users. Provide both AVI and QuickTime versions of your video files. Provide both WAV and AU versions of your audio files.

Test your media clips on different browsers and browser versions.

Applet

- is a small program designed to execute within another application.

INSERTING A JAVA APPLET

To insert a Java applet, use the following syntax:

.

Where file.class is the name of the applet that is called by the browser, and the WIDTH and HEIGHT properties define the size of the applet window a it appears on the Web page.

If the applet requires some parameters in order to function, enter the parameter values with the following syntax:

where the NAME property is the name of the particular parameter, and the VALUE property is the value that you want to assign to it.

INSERTING A JAVA APPLET

To access a Java applet located in a different folder from the one that contains the current HTML file, insert the following property in the tag:

CODEBASE = URL

Where URL is the location of the file.class file.

CREATING A MARQUEE WITH INTERNET EXPLORER

To create a marquee (a box of scrolling text) for the Internet Explorer browser, without using a Java applet, use the following HTML tag:

Marquee Text

where Marquee Text is the text that will scroll from right to left across the box.

CREATING A MARQUEE WITH INTERNET EXPLORER

To control the appearance and size of the marquee, insert the following properties into the tag:

BGCOLOR = color WIDTH = value HEIGHT = value

where BGCOLOR property controls the background color of the marquee box, and the WIDTH and HEIGHT properties define the boxs dimensions.

CREATING A MARQUEE WITH INTERNET EXPLORER

To create a marquee (a box of scrolling text) for the Internet Explorer browser, without using a Java applet, use the following HTML tag:

Marquee Text

where Marquee Text is the text that will scroll from right to left across the box.

CREATING A MARQUEE WITH INTERNET EXPLORER

To control the placement of the marquee with the surrounding text, use the properties:

HSPACE = value VSPACE = value ALIGN = alignment

where the HSPACE and VSPACE properties define the amount of horizontal and vertical space around the box (in pixels), and the ALIGN property determines the alignment of the box with the surrounding text.

CREATING A MARQUEE WITH INTERNET EXPLORER

To control the behavior of text within the marquee, use the properties:

BEHAVIOR = item DIRECTION = item LOOP = value

where BEHAVIOR is either SCROLL (to continuously scroll the text across the box), SLIDE (to slide the text across the box, or ALTERNATE (to bounce the text back and forth across the box). The DIRECTION property is either LEFT or RIGHT, defining in which direction the text moves. The LOOP value determines how often the text moves across the box, and either a digit or INFINITE.

CREATING A MARQUEE WITH INTERNET EXPLORER

To control the speed of the text within the marquee, use the properties:

SCROLLAMOUNT = value SCROLLDELAY = value

Where SCROLLAMOUNT is the amount of space (in pixels) that the text moves each time it advances across the page, and SCROLLDELAY is the amount of time, in milliseconds, between text advances.
