## Descripziun

a3 Lazy Load is a Mobile Oriented, very simple to use plugin that will speed up 
sites page load speed. The more content heavy your site the better the plugin will
perform and the more you will see the improvements in performance. See [this demo](http://ressio.github.io/lazy-load-xt/demo/stresstest1000img.htm)
of a page with 1,000 images (yes 1,000 images) to load.

a3 Lazy Load is inspired by and powered by the ressio [Lazy-Load-xt JavaScript](https://github.com/ressio/lazy-load-xt).

#### 100% COMPATABLE WITH WORDPRESS 6.0

WordPress 5.5 introduced lazy loading for all images uploaded to a sites media library
and 5.7 introduces Core lazy load for iframes and 5.9 contained performance enhancements.
a3 Lazy Load Image options work side-by-side with these, but then enhances it by
lazy loading all the images loaded from outside of the media library, or on older
browsers that do not support the new WP attribute and any iframes or videos that
are not lazy loaded by WordPress.

#### DISABLE WORDPRESS LAZY LOAD

The plugin includes an option to completely disable WordPress Core Lazy Load if 
that is what you want to do.

#### IMAGE LAZY LOAD

For more flexibility when ON you can choose to ON | OFF lazy load all images that
are not loaded from the WordPress media Library in:

 * Post, Pages and Custom Post Types (All Content areas)
 * Widgets (Sidebar, header and footer)
 * Apply to post thumbnails
 * Apply to gravatars

#### HORIZONTAL SCROLL

Supports lazy loading of images in containers that use horizontal scroll. The admin
Images options has a section where you enter the classname or ID of the container
that uses horizontal scroll.

#### VIDEO LAZY LOAD

From the a3 lazy Load admin panel turn Video Support ON | OFF. When ON you can choose
to ON | OFF lazy load for videos in

 * Video embeded by URL in Post and Pages (All Content areas)
 * Video in Widget types, Text Widget and HTML Widgets.

#### iFRAME LAZY LOAD

a3 Lazy Load has built in support for content that is added by iframe from any source
in content and widgets and will lazy load any iframe that WordPress core does not
load. Examples

 * WordPress embedded media
 * Facebook Like boxes with profiles, Like buttons, Recommend
 * Google+ Profile
 * Google Maps

#### POST EMBED

 * Fully compatible with WordPress embed post on any site feature introduced in 
   version WP version 4.4
 * Makes embed post load much faster

#### WORDPRESS AMP

 * Built in auto support for WordPress AMP plugin
 * Built in support for Better AMP plugin
 * There are no setting options for exclude /amp – Lazy Load is just never applied
   to the /amp endpoint
 * When the url is loaded in browser without /amp Lazy Load is applied

#### JETPACK SITE ACCELERATOR (Photon)

This is an option that you turn on as the Jetpack Accelerator (Photon CDN images)
has its own lazy load feature that needs to be OFF first to be able use a3 Lazy 
Load as your lazy Load engine. Some users prefer to use a3 Lazy Load as it applies
Lazy Load to videos and iframes as well as images.

#### WebP IMAGES

a3 Lazy Load has built in automatic support for WebP images. There are no settings
for this as a3 Lazy Load will automatically detect if an image has a WebP version
and lazy load the WebP version. If no WebP image exists, the appropriate jpg or 
png version will be lazy loaded. Also fully support browser detection of WebP.

#### LAZY LOAD EFFECTS

a3 Lazy Load gives you the option to lazy load images with a FADE IN or SPINNER 
effect

 * FADEIN [see demo](http://ressio.github.io/lazy-load-xt/demo/fadein.htm)
 * SPINNER [see demo](http://ressio.github.io/lazy-load-xt/demo/spinner.htm)
 * Option to create a custom Lazy Load pre-load background colour

#### PERFORMANCE TWEAKS

a3 Lazy Load gives you the option to load its script from your sites HEAD or from
the FOOT.

 * Note that your theme must have the wp_footer() function if you select FOOTER 
   load.
 * Note the plugin CSS is always loaded from the HEAD.

#### EXCLUDE IMAGES & VIDEO

a3 Lazy Load allows you to easily exclude any image or video by class name from 
having the Lazy Load effect applied. [See FAQ’s](https://wordpress.org/plugins/a3-lazy-load/#faq-header)

#### JAVASCIPT DISABLED FALLBACK

a3 Lazy Load has built in Noscript fallback if user has JavaScript turned off in
their browser. Developers who use underscore.js in their applications can use the
Noscript parameter to exclude their plugins content from Lazy Load.

#### THEME & PLUGIN COMPATIBILITY

a3 Lazy Load works with any WordPress theme that follows the WordPress Theme Codex.
However, many Theme & Plugin developers will use a custom written function to add
objects, example the theme has a home page with layout created by a custom function
they have written. a3 Lazy Load cannot know what these functions are and so cannot
apply to the objects loaded by that custom function.

If your images or objects not being Lazy Loaded in a certain section of your site,
but are Lazy Loaded everywhere else you will know this is the cause. Please if this
happens raise a support ticket with the developer, explaining that they just need
to add a simple tag to their custom functions so that a3 Lazy Load apply to their
custom function and be fully compatible. [Here is a list](https://wordpress.org/plugins/a3-lazy-load/#faq-header)
of a3 lazy Load filter tags to include in your ticket to make it easy for the developer.

Don’t forget when a developer does add full compatibility with a3 Lazy Load please
let us know via a support ticket on this forum and we will add them to the list 
below.

## FAQ

### How do I exclude individual objects from Lazy Load?

Images, Videos / iframes can be excluded from Lazy Load by existing classnames or
if none exist exclusions can be done manually via exclusion `skip-lazy` classname
or `data-skip-lazy` attribute. Examples
 Exclude by classname `&#x3C;img class="
skip-lazy"&#x3E; , &#x3C;video class="skip-lazy"&#x3E;` Exclude by attribute `&#
x3C;img data-skip-lazy&#x3E; , &#x3C;video data-skip-lazy&#x3E;`

### Why are some images, videos, objects not Lazy Loaded?

a3 Lazy Load can only be applied to objects that are added using core WordPress 
functions. If your theme or a plugin developer adds objects such as images or videos
via a custom written function, a3 lazy Load cannot know what that custom function
is and hence cannot Lazy Load the object.

So if you see object not being lazy loaded please check first if those objects are
loaded by the theme or a plugin. If they are, you can be confident that they are
loaded by a custom function.

If this is the case, please help yourself and other a3 lazy Load users by raising
a support ticket with the developer and ask them to add an a3 Lazy Load filter tag
to their function to allow a3 Lazy Load to find it and apply to the object.

Below is a list of available a3 Lazy Load filters to use and pass onto the developer.

### Filter tags to apply lazy load

Apply lazy load for images in content.
 a3_lazy_load_images Example: apply_filters(‚
a3_lazy_load_images‘, $your_content, null );

Apply lazy load for videos and iframe from content.
 a3_lazy_load_videos Example:
apply_filters( ‚a3_lazy_load_videos‘, $your_content, null );

Apply lazy load for all images, videos and iframe from content
 a3_lazy_load_html
Example: apply_filters( ‚a3_lazy_load_html‘, $your_content, null );

### Filter Tags to Exclude by Theme Class name

Filter tags to add to class name of theme to exclude lazy load on images or videos.

a3_lazy_load_skip_images_classes a3_lazy_load_skip_videos_classes

others.
