Introduced in HTML5

Summary

The HTML <progress> Element is used to view the completion progress of a task. While the specifics of how it's displayed is left up to the browser developer, it's typically displayed as a progress bar. Javascript can be used to manipulate the value of progress bar.

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 zero and be a valid floating point number.
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.

You can use the -moz-orient property to specify whether the progress bar should be rendered horizontally (the default) or vertically. The :indeterminate pseudo-class can be used to match against indeterminate progress bars.

Examples

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

[1] Gecko provides the ::-moz-progress-bar pseudo-element, which lets you style the part of the interior of the progress bar representing the amount of work completed so far.
Prior to Gecko 14.0 (Firefox 14.0 / Thunderbird 14.0 / SeaMonkey 2.11), the <progress> element was incorrectly classified as a form element, and therefore had a form attribute. This has been fixed.

[2] Gecko provides the ::-moz-progress-bar pseudo-element, which lets you style the part of the interior of the progress bar representing the amount of work completed so far.

[3] Safari on iOS does not support indeterminate progress bars (they are rendered like 0%-completed progress bars).
