HTML <param> Tag

The HTML <param> tag is used for passing parameters to an embedded object.

The <param> tag does not represent anything on its own. It is used with the <object> tag to provide parameters.


The <param> tag is written as <param name="" value=""> (no end tag). The name and value attributes provide a name/value pair that the <object> element can use.

The <param> must be nested inside an <object> element, before any "flow content".

Like this:


You can use the <param> element to pass parameters to your embedded objects.

Here, we use the <param> tag to embed a music file, and the <param> element to pass parameters to the <param> element. We tell it not to display audio controls (name="controller" value="true") and to start playing automatically (i.e. name="autoplay" value="false).


Attributes can be added to an HTML element to provide more information about how the element should appear or behave.

There are 3 kinds of attributes that you can add to your HTML tags: Element-specific, global, and event handler content attributes.

The <param> element accepts the following attributes.

Element-Specific Attributes

This table shows the attributes that are specific to the <param> tag/element.

nameDefines the name of the parameter. Required attribute.
valueSpecifies the value of the parameter. Required attribute.

Global Attributes

The following attributes are standard across all HTML5 elements. Therefore, you can use these attributes with the <param> tag , as well as with all other HTML tags.

For a full explanation of these attributes, see HTML 5 global attributes.

Event Handler Content Attributes

Event handler content attributes enable you to invoke a script from within your HTML. The script is invoked when a certain "event" occurs. Each event handler content attribute deals with a different event.

Below are the standard HTML5 event handler content attributes.

Again, you can use any of these with the <param> element, as well as any other HTML5 element.

For a full explanation of these attributes, see HTML 5 event handler content attributes.

Differences Between HTML 4 & HTML 5

HTML5 does not support the type and valuetype attributes, which were supported in HTML 4.

To see more detail on the two versions see HTML5 <param> Tag and HTML4 <param> Tag. Also check out the links to the official specifications below.


Here's a template for the <param> tag with all available attributes for the tag (based on HTML5). These are grouped into attribute types, each type separated by a space. In many cases, you will probably only need one or two (if any) attributes. Simply remove the attributes you don't need.

For more information on attributes for this tag, see HTML5 <param> Tag and HTML4 <param> Tag.

Here are the official specifications for the <param> element.

What's the Difference?

W3C creates "snapshot" specifications that don't change once defined. So the HTML5 specification won't change once it becomes an official recommendation. WHATWG on the other hand, develops a "living standard" that is updated on a regular basis. In general, you will probably find that the HTML living standard will be more closely aligned to the current W3C draft than to the HTML5 specification.
