Easings

Easing functions specify the speed at which an animation progresses at different points within the animation.

Blind Effect

The blind effect hides or shows an element by wrapping the element in a container, and “pulling the blinds”

.toggleClass()

Add or remove one or more classes from each element in the set of matched elements, depending on either the class’s presence or the value of the switch argument, while animating all style changes.
