The <progress> HTML element is used to represent the completion progress of a task, such as a download or file upload, as a visual indicator. It is a self-contained, semantic element that provides a way to display the progress of a task to the user. The <progress> element is part of the HTML5 specification and is often rendered as a progress bar by browsers.

<label for="file">File Upload Progress:</label>
<progress id="file" value="70" max="100">70%</progress>Valid Attributes for <progress>
