HTML <progress> Tag

The HTML <progress> tag is used to represent the completion progress of a task or process, such as a file upload or a data load. This tag is a great way to visually inform users of ongoing operations, providing a better user experience by displaying the status of a task. The <progress> element shows the progress bar, allowing users to see how much of a task has been completed.

Syntax of the <progress> Tag

html
<progress value="currentValue" max="maxValue">Fallback Text</progress>
  • value: Specifies how much of the task is complete (current progress).
  • max: Defines the total value or the maximum of the task (if not specified, the default is 1).

The text within the <progress> tag (fallback text) is displayed in older browsers that do not support this element.

Attributes of the <progress> Tag

The <progress> tag supports several attributes that allow for customization and control of the progress bar's behavior:

AttributeDescription
valueSpecifies the current value or progress of the task.
maxDefines the maximum value (100%, default value is 1).
Global AttributesSupports other global attributes like class, id, style for styling.
  • Global Attributes: The <progress> tag can also accept global attributes like class, id, and style, which allows for greater flexibility in styling and identification.

Examples of HTML <progress> Tag

Example 1: Basic Progress Bar

html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Basic Progress Bar</title>
</head>
<body>
    <label for="fileProgress">File Upload Progress:</label>
    <progress id="fileProgress" value="40" max="100">40%</progress>
</body>
</html>

In this example, the <progress> tag shows the completion status of a file upload, which is 40% complete out of a total of 100%.

Example 2: Progress Bar Without the max Attribute

html
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Progress Without Max Attribute</title>
</head>
<body>
    <label for="loading">Loading Progress:</label>
    <progress id="loading" value="0.7">70%</progress>
</body>
</html>

In this example, the max attribute is omitted, meaning the default value of 1 is used. The progress bar represents 70% completion of the task.
