<progress>: The Progress Indicator element
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
The <progress>
HTML element displays an indicator showing the completion progress of a task, typically displayed as a progress bar.
Try it
<label for="file">File progress:</label> <progress id="file" max="100" value="70">70%</progress>
label { padding-right: 10px; font-size: 1rem; }
Attributes
This element includes the global attributes.
max
This attribute describes how much work the task indicated by the
progress
element requires. Themax
attribute, if present, must have a value greater than0
and be a valid floating point number. The default value is1
.value
This attribute specifies how much of the task that has been completed. It must be a valid floating point number between
0
andmax
, or between0
and1
ifmax
is omitted. If there is novalue
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')
.
Accessibility
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.
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>

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.
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>

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