Animate any Elements on scroll using the popular AOS JS library simply by adding class names.

This plugin helps you integrate easily with AOS JS library to add any AOS animations (on scroll animation) to WordPress.

It should work well with the native gutenberg core blocks or any page builder (tested with GenerateBlocks and Elementor) that provides an input field for adding custom class names to elements.

About AOS

AOS is a small JavaScript library built by Michał Sajnóg that allows you to add animated effects to HTML elements when they come into view as the user scrolls down a webpage. AOS provides a set of predefined animations using CSS that can be easily applied to elements using simple data attributes in the HTML code.

Check out the AOS demo and documentation.

How to add Animations?

Simply add the desired AOS animation to your element class name with “aos-” prefix and the plugin will add the corresponding aos attribute to the element tag.

Fade animations:

  • fade: aos-fade
  • fade-up: aos-fade-up
  • fade-down: aos-fade-down
  • fade-left: aos-fade-left
  • fade-right: aos-fade-right
  • fade-up-right: aos-fade-up-right
  • fade-up-left: aos-fade-up-left
  • fade-down-right: aos-fade-down-right
  • fade-down-left: : aos-fade-down-left

Flip animations:

  • flip-up: aos-flip-up
  • flip-down: aos-flip-down
  • flip-left: aos-flip-left
  • flip-right: aos-flip-right

Slide animations:

  • slide-up: aos-slide-up
  • slide-down: aos-slide-down
  • slide-left: aos-slide-left
  • slide-right: aos-slide-right

Zoom animations:

  • zoom-in: aos-zoom-in
  • zoom-in-up: aos-zoom-in-up
  • zoom-in-down: aos-zoom-in-down
  • zoom-in-left: aos-zoom-in-left
  • zoom-in-right: aos-zoom-in-right
  • zoom-out: aos-zoom-out
  • zoom-out-up: aos-zoom-out-up
  • zoom-out-down: aos-zoom-out-down
  • zoom-out-left: aos-zoom-out-left
  • zoom-out-right: aos-zoom-out-right

Animation Settings

By default, the global animation settings are

  • offset: -100
  • duration: 1100
  • easing: ease
  • delay: 0
  • once: true

you can change that using filter:

add_filter( 'aos_init', function($aos_init) {
    return '
    var aoswp_params = {
        "offset":"200",
        "duration":"1800",
        "easing":"ease-in-out",
        "delay":"0",
        "once": false};
    ';
} );

or add the extra classes below to the element for individual settings. The plugin will add the corresponding aos attribute to the tag.

  • once=true: aos-once-true

To Disable Animations On Specific Device

  • To disable animations on certain elements on devices larger than 767px, simply add aoswp-disable-desktop class name to the element tag
     
  • To disable animations on certain elements on devices smaller than 766px, simply add aoswp-disable-mobile class name to the element tag
     

  • To disable animations site-wide / per page basis on specific devices:
    add this lines to your css files:

    @media ( your media query ) {

        html:not(.no-js) .aoswp-enabled [data-aos] {
        opacity: 1!important;
        -webkit-transform: none!important;
        transform: none!important;
        transition: none!important;
        transition-timing-function: unset!important;
        transition-duration: unset!important;
        transition-property: none!important;
    }

    }

 

Note

  • Both AOS JavaScript and CSS will only be loaded if there is ‘aos-‘ in the page’s html. So this plugin will not add bloat to pages that do not use/need the AOS animations.
     
  • Although the AOS library is already lightweight, the CSS and JS in this plugin are delay-able, so it won’t hurt your site’s performance at all. (You can use Optimize More! to delay the CSS and JS)

Disclaimer

This plugin doesn’t add anything to your database and won’t do any permanent change to your HTML, so you can safely deactivate and delete it when you no longer need it.
