The <iframe> and <object> tags can be used to embed another document within the current page.

HTML iframe tag

The <iframe> is used to add and display the content of another document, or webpage within the current HTML document.
- Example:

<h4>Example iframe</h4>
<p>The following content is into an IFRAME element.</p>

<iframe width='400' height='300' src=''></iframe>

Attributes of <iframe>

The following attributes can be used in the <iframe> tag:

- Example, <iframe> with 'srcdoc'.
<h4>Example iframe with srcdoc</h4>
<p>The following content is into an IFRAME element with srcdoc attribute, which replaces the content from the 'src' address.</p>

<iframe width='400' height='300' src='' srcdoc='<h3>Content from srcdoc</h3>'></iframe>

The <iframe> positioning and style is made with CSS properties, via the 'id', 'class' or 'style' attributes.

HTML object tag

The <object> tag is used for embedding media contents on a web page (images, Java applets, Flash, PDF, movie, or even another HTML file).
This element is designed to include any sort of document. It uses the type attribute to indicate the 'mime type', and the data attribute to indicate the source of the document (its URI).

<h4>Example HTML object element</h4>
<p>In the OBJECT tag of this HTML document it is added a SWF file (a game).</p>

<object width='550' height='400' data='html/cubilus.swf' type='application/x-shockwave-flash'></object>

In <object> you can add the following attributes:

- Example, shows a PDF document in HTML page:
<h4>Example PDF in HTML object</h4>
<p>In the OBJECT tag of this HTML document it is added a PDF file.</p>

<object type='application/pdf' data='blog/101_zen_stories.pdf' width='400' height='280'>PDF Document.</object>
