The STANDBY attribute is also utilized in the example. The TYPE attribute specifies the media type of the resource referenced by the DATA attribute while the CODETYPE attribute specifies the media type of the CLASSID data. The preceding example also makes use of the TYPE and CODETYPE attributes to allow browsers to avoid requesting a file that they cannot render. Note that OBJECT is backwards compatible with pre-HTML 4.0 browsers since they will ignore the tags and render the innermost alternate content (the text in the example). An image is given for browsers that cannot show the Java or Python applets, and text is used as a final alternative if images are not loaded. A Java version is provided as an alternative for browsers that do not support Python applets. In the example, a Yahtzee game written in Python is used if the browser supports it. This example also demonstrates the use of alternate content for browsers that cannot display the embedded object.
Java applets, Python applets, and ActiveX controls all provide implementations for the embedded object, and so are specified with the CLASSID attribute, as in the following example: The CLASSID attribute may be used to specify an implementation for the object. Many browsers require the WIDTH and HEIGHT attributes for all objects embedded using OBJECT. The value may be given in pixels or as a percentage of the parent element's width or height. The WIDTH and HEIGHT attributes define the dimensions of the object. Relative URIs are interpreted with respect to the CODEBASE attribute if it is given. OBJECT's DATA attribute specifies the URI of the embedded object. OBJECT is intended to replace the more specific IMG and APPLET elements, as well as the proprietary EMBED and BGSOUND elements, though a lack of browser support and severe bugs in supporting browsers make the other elements a better choice in many cases. The OBJECT element is used to include objects such as images, audio, videos, Java applets, and Flash animations.

This example takes advantage of the fact the object elements may be nested Example 2: An object includes non-text content with a text alternative Įxample 3: The image object has content that provides a brief description of the function Here is some text that describes the object and its operation.
