<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
progresselement requires. Themaxattribute, if present, must have a value greater than0and 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
0andmax, or between0and1ifmaxis omitted. If there is novalueattribute, 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
