Mprogress.js

Built entirely with vanilla JavaScript and CSS3, as stated in the README, ensuring no external library dependencies and a minimal footprint for broad compatibility.

Faithfully implements Google's Material Design progress indicators with four distinct types—determinate, buffer, indeterminate, and query—matching the official specifications shown in the demo.

Offers intuitive methods like start(), end(), set(), and inc() for easy control, demonstrated in the basic usage examples for quick integration.

Supports customization through options like template selection, parent container targeting, and auto-start, allowing adaptation to various loading scenarios without complex setup.
