<progress>: The Progress Indicator element

The <progress> HTML element displays an indicator showing the completion progress of a task, typically displayed as a progress bar.

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.

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.

Examples

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

<!-- OR -->
<br />

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

Result

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.

Examples

<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>
