Jarallax is a feature-rich JavaScript library for easily creating and customizing parallax scrolling effects.

The library enables us to manipulate CSS using keyframes and it supports custom controllers.

These controllers, compared to time-based animations, allows us to decide the events that animations will react to (scrolling, mouse gestures, etc.).

And, besides JavaScript animations, it can also use CSS-powered ones for a better performance.

P.S. The library makes use of jQuery.

Codrops, a creative web design and development blog, has created a detailed tutorial on creating a beautiful slider powered only by HTML and CSS3.

The slider not only uses the transition property but also changes the background-position of the given background images accordingly to create a parallax effect.

Slides can be browsed either with the bullet-navigation (styled radio inputs) and/or with the prev-next links.

Both of the effects are very smooth and the slider adapts itself perfectly to any width (responsive).
