This element includes the global attributes.
This attribute describes how much work the task indicated by the
progresselement requires. The
maxattribute, if present, must have a value greater than zero and be a valid floating point number.
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
maxis omitted. If there is no
valueattribute, 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
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.
<progress value="70" max="100">70 %</progress>

On Windows, the resulting progress looks like this:

 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.
