Attributes

This element includes the global attributes.

max

This attribute describes how much work the task indicated by the progress element requires. The max attribute, if present, must have a value greater than 0 and be a valid floating point number. The default value is 1.

value

This attribute specifies how much of the task that has been completed. It must be a valid floating point number between 0 and max, or between 0 and 1 if max is omitted. If there is no value attribute, the progress bar is indeterminate; this indicates that an activity is ongoing with no indication of how long it is expected to take.

Note: Unlike the <meter> element, the minimum value is always 0, and the min attribute is not allowed for the <progress> element.

Note: The :indeterminate pseudo-class can be used to match against indeterminate progress bars. To change the progress bar to indeterminate after giving it a value you must remove the value attribute with element.removeAttribute('value').

Examples

<progress value="70" max="100">70 %</progress>

Accessibility Concerns

Labelling

In most cases you should provide an accessible label when using <progress>. While you can use the standard ARIA labelling attributes aria-labelledby or aria-label as you would for any element with role="progressbar", when using <progress> you can alternatively use the <label> element.

Note: Text placed between the element's tags is not an accessible label, it is only recommended as a fallback for old browsers that do not support this element.

Example

  <label>Uploading Document: <progress value="70" max="100">70 %</progress></label>

  <!-- OR -->

  <label for="progress-bar">Uploading Document</label>
  <progress id="progress-bar" value="70" max="100">70 %</progress>

Describing a particular region

If the <progress> element is describing the loading progress of a section of a page, use aria-describedby to point to the status, and set aria-busy="true" on the section that is being updated, removing the aria-busy attribute when it has finished loading.

Example

  <div aria-busy="true" aria-describedby="progress-bar">
    <!-- content is for this region is loading -->
  </div>

  <!-- ... -->

  <progress id="progress-bar" aria-label="Content loading..."></progress>
