Linear Progress

Linear Progress indicators, commonly known as loaders, express an unspecified wait time or display the length of a process.

Introduction

Progress indicators inform users about the status of ongoing processes, such as loading an app, submitting a form, or saving updates.

The LinearProgress is indeterminate by default, indicating an unspecified wait time. To actually have it represent how long an operation will take, use the determinate mode.

The animations of the components rely on CSS as much as possible to work even before the JavaScript is loaded.
