HTML <progress> Tag

The HTML <progress> tag represents the progress of a task.

The <progress> element can be used in conjunction with JavaScript to display the progress of a task or process as it is underway.

The <progress> tag should not be confused with the <meter> tag (which represents a gauge).


The <progress> tag is typically written as <progress value="" max=""></progress> with any contents inside the start and end tags. This content could be the current value and/or maximum value that can be displayed to legacy browsers (i.e. browsers that don't support the <progress> element).

The value attribute represents the current value (i.e. where the progress is currently at). If you omit this attribute, the progress bar becomes "indeterminate", and it will not display any progress (but most browsers will display an animated bar to indicate to the user that it's trying...).

The max attribute represents the total amount (i.e. where the progress bar's value will be when it's finished).

Like this:


Basic tag usage

Indeterminate Progress Bar

You can make a progress bar "indeterminate" by removing the value attribute.

JavaScript Example

Here's a quick example that uses JavaScript to modify the value of the <progress> element on the fly.


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 <progress> element accepts the following attributes.

Element-Specific Attributes

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

valueSpecifies how much of the task has been completed.
maxSpecifies how much work the task requires in total.

Global Attributes

The following attributes are standard across all HTML5 elements. Therefore, you can use these attributes with the <progress> 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 <progress> 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

The <progress> tag is new in HTML5.

For more detail on this element, see HTML5 <progress> Tag. Also check out the links to the official specifications below.


Here's a template for the <progress> 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 <progress> Tag.

Here are the official specifications for the <progress> 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.
