MORE INFORMATION

Web authors use tags to define the layout and content of Web pages. Each tag is an element of the Hypertext Markup Language (HTML). The <Embed> tag is a non-standard HTML tag that is used to embed documents of any type in an HTML document. You need to have a program that can view the data installed correctly on your computer. The <Embed> tag must appear inside the body of the HTML document.

Attributes provide additional information used by tags. The SRC attribute is a required attribute for the <Embed> tag and is used to refer to the URL of a data object embedded in the Web page. The TYPE attribute is not supported by Internet Explorer. It is used in conjunction with the <Embed> tag to specify a particular Multipurpose Internet Mail Extensions (MIME) type. MIME is used to start a program through a browser.

For information about the use of the <Embed> tag with Internet Explorer 4.0 and 4.01, visit the following Microsoft Web page:
