JavaScript animations as a fallback for CSS animations

We might have to create animations for browsers that do not have support for CSS animations and transitions yet. It might be part of a project's requirements.

In this case, we can still use JavaScript animations as a fallback for CSS animations. However, what if we add a CSS animation and a JavaScript animation for the same element and the browser has support for CSS animations?

We don't want to display the same animation twice, so we will use Modernizr, a JavaScript library that detects HTML5 and CSS3 features in the user's browser.

Note

Learn more about Modernizr at http://modernizr.com.

In such cases, we will trigger the JavaScript animations only if CSS transitions are not supported by the browser.
