Not every loading bar is as subtle as this one.

Simple yet effective. The loader is a simple slider, however notice how well it fits to the logo badge of the site. While the page is loading, bubbles are floating all over the place.

The loader design fits perfectly to the overall design of the site.

Simple, but visually appealing.

This loader is simple, but corresponds to the theme of the site.

This preloader bar grows diagonally.
