Object Element: Embedding External Resources
The <object> HTML element is used to embed external resources, such as images, videos, audio, documents, or interactive content, into a webpage. It is a versatile element that can serve as a container for various types of media and applications, including plugins, Java applets, and other web-based content. The <object> element can also be used to embed another HTML document within the current document.
Usage and Characteristics
The <object> element is a block-level element and can contain fallback content, which is displayed if the external resource cannot be loaded or is not supported. This fallback content can include alternative text, links, or other HTML elements. Here is an example of how the <object> tag can be used:
<object data="example.pdf" type="application/pdf" width="600" height="400">
<p>Your browser does not support PDFs. Please download the PDF to view it: <a href="example.pdf">Download PDF</a>.</p>
