LazyLoad makes it easy and painless to lazily load one or more external
|
|
|
|
|
JavaScript or CSS files on demand either during or after the rendering of a web
|
|
|
|
|
page.
|
|
|
|
|
|
|
|
|
|
Supported browsers include Firefox 2+, IE6+, Safari 3+ (including Mobile
|
|
|
|
|
Safari), Google Chrome, and Opera 9+. Other browsers may or may not work and
|
|
|
|
|
are not officially supported.
