README

An extention to create AWESOME parallax effects.

Installation

The preferred way to install this extension is through composer.

Either run

composer require --prefer-dist dmstr/yii2-parallax "*"

or add

"dmstr/yii2-parallax": "*"

to the require section of your composer.json file.

Register desired asset bundle in view
Set the x and y to define direction and velocity. An extra optional parameter (startCondition) tells the element when it should start moving. use "asap" to move the element as soon as the scroll event fires. Use "visible" (default value) for those elements that should move as soon they become visible in the viewport.
Scroll to see the AWESOME effect.

[data-parallax="{x}, {y}, {when}"]

Example with 3 parallax elements

<div data-parallax="0.2, -0.2, asap"></div>
<div data-parallax="0.2, -0.2, visible"></div>
<div data-parallax="0.2, -0.2"></div>

TIP: try it with css transitions on transform to create nicer effect.
TIP: to make realistic parallax effects, closer (alsor bigger) elements should move faster than elements tha are farther (also smaller).

Example widget usage

<?php Parallax::begin(['x' => 0.1, 'y' => -0.2, , 'startCondition' => 'visible']); ?>
<?= '... some content' ?>
<?php Parallax::end(); ?>
