Lazy-Load-Images-without-jQuery

About

Lazy load your images without the overhead of a framework. Optionally, send mobile-optimized images to smaller screens. Tested on IE7+, Firefox, Chrome, iOS.

Original code from Mike Pulaski.

Usage

1) Include lazyload.min.js or inline it.

2) Add .lazy-load and data-src to each of your <img> tags. Optionally add data-src-mobile, a placeholder src, and a fallback image.

<img class="lazy-load" data-src="lazy.jpg" data-src-mobile="lazy-small.jpg" src="blank.gif" />
<noscript><img src="lazy.jpg" /></noscript>

3) Add CSS3 for an animated fade-in:

.lazy-load, .lazy-loaded {
  -webkit-transition: opacity 0.3s;
  -moz-transition: opacity 0.3s;
  -ms-transition: opacity 0.3s;
  -o-transition: opacity 0.3s;
  transition: opacity 0.3s;
  opacity: 0;
}

.lazy-loaded { opacity: 1; }
