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.
Syntax
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:
Example
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
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.
| Attribute | Description |
|---|---|
| name | Defines the name of the parameter. Required attribute. |
| value | Specifies 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.
- accesskey
- class
- contenteditable
- contextmenu
- dir
- draggable
- dropzone
- hidden
- id
- inert
- itemid
- itemprop
- itemref
- itemscope
- itemtype
- lang
- spellcheck
- style
- tabindex
- title
- translate
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.
- onabort
- oncancel
- onblur
- oncanplay
- oncanplaythrough
- onchange
- onclick
- oncontextmenu
- ondblclick
- ondrag
- ondragend
- ondragenter

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.
Template
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.

Specifications
Here are the official specifications for the <param> element.
- HTML5 Specification (W3C)
- HTML Living Standard (WHATWG)
- Current W3C Draft (the next version that is currently being worked on)
- HTML 4 (W3C)
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.
