jquery.revealer

Animate elements to and from display: none!

Requirements

This plugin requires jQuery, and the jquery.trend.js plugin.

Usage

$('button.show').on('click', function() {
  $('#my-element').revealer('show');
});

$('button.hide').on('click', function() {
  $('#my-element').revealer('hide');
});

$('button.toggle').on('click', function() {
  $('#my-element').revealer('toggle');
});

Revealer doesn't actually change your element's styles--instead it adds classes in an order that allows you to transition smoothly.

####.animating Apply your initial transition state (e.g. opacity: 0;) as well as your transition: property with this class.

####.visible Apply your final transition state (e.g. opacity: 1) to this state.

caveat

We assume an inital default state of display: none. Therefore the above classes should also include a display: block; property.

Different transitions on in and out

To apply different transitions for enter and leave, use .animating-in and .animating-out to declare different initial transition states. .visible will then include the final state for both in and out.

Setting a state without a transition

To skip the transitioning and force a specific display state, you may pass true as the second parameter to show, hide, or toggle:

$('.el').revealer('show', true);

Get the current state

To check if an element is currently visible, use the isVisible function:

var visible = $('.el').revealer('isVisible');

Example

.element-to-reveal {
  display: none;

  &.animating,
  &.visible {
    display: block;
  }

  // initial state for enter transition
  &.animating-in {
    transform: translateX(-100%);
    transition: transform 0.3s ease;
  }

  // initial state for leave transition
  &.animating-out {
    opacity: 0;
    transition: opacity 0.2s ease;
  }

  // final states for both in and out
  &.visible {
    transform: translateX(0);
    opacity: 1;
  }
}
