Material-Preloader

The plugin offers simple methods like `.on()` and `.off()` for controlling the preloader, making it straightforward to add to existing jQuery projects with minimal code, as shown in the usage examples.

It allows detailed customization of colors, position, height, and animation speeds through options such as `col_1` to `col_4` and `fadeIn`, enabling visual alignment with various design schemes.

It replicates the unique Material Design loading bar from Google Inbox, providing a polished and modern loading experience that enhances user engagement compared to generic spinners.

With only a CSS file and a JS file required, plus minimal configuration, it's a lightweight solution for adding animated loading indicators without building custom animations from scratch.
