HTML <progress> Tag
<progress> tag represents the progress of a task.
<progress> tag should not be confused with the
<meter> tag (which represents a gauge).
<progress> tag is typically written as
<progress value="" max="">
</progress> with any contents inside the start and end tags. This content could be the current value and/or maximum value that can be displayed to legacy browsers (i.e. browsers that don't support the
value attribute represents the current value (i.e. where the progress is currently at). If you omit this attribute, the progress bar becomes "indeterminate", and it will not display any progress (but most browsers will display an animated bar to indicate to the user that it's trying...).
max attribute represents the total amount (i.e. where the progress bar's value will be when it's finished).
Basic tag usage
Indeterminate Progress Bar
You can make a progress bar "indeterminate" by removing the
<progress> element on the fly.
Attributes can be added to an HTML element to provide more information about how the element should appear or behave.
<progress> element accepts the following attributes.
|Specifies how much of the task has been completed.|
|Specifies how much work the task requires in total.|
The following attributes are standard across all HTML elements. Therefore, you can use these attributes with the
<progress> tag , as well as with all other HTML tags.
For a full explanation of these attributes, see HTML 5 global attributes.
Event handler content attributes enable you to invoke a script from within your HTML. The script is invoked when a certain "event" occurs. Each event handler content attribute deals with a different event.
Most event handler content attributes can be used on all HTML elements, but some event handlers have specific rules around when they can be used and which elements they are applicable to.
For more detail, see HTML event handler content attributes.
