HTML <progress> Tag
The HTML <progress>
tag represents the progress of a task.
The <progress>
element can be used in conjunction with JavaScript to display the progress of a task or process as it is underway.
The <progress>
tag should not be confused with the <meter>
tag (which represents a gauge).
Syntax
The <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 <progress>
element).
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...).
The max
attribute represents the total amount (i.e. where the progress bar's value will be when it's finished).
Like this:
Examples
Basic tag usage
Indeterminate Progress Bar
You can make a progress bar "indeterminate" by removing the value
attribute.
JavaScript Example
Here's a quick example that uses JavaScript to modify the value of the <progress>
element on the fly.
Attributes
Attributes can be added to an HTML element to provide more information about how the element should appear or behave.
The <progress>
element accepts the following attributes.
Attribute | Description |
---|---|
value | Specifies how much of the task has been completed. |
max | Specifies how much work the task requires in total. |
