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. Themax
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 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.
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] 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).
