Modernizr vs fancybox: What are the differences?

Developers describe Modernizr as "Respond to your user’s browser features". It’s a collection of superfast tests or detects as we like to call them which run as your web page loads, then you can use the results to tailor the experience to the user. It tells you what HTML, CSS and JavaScript features the user’s browser has to offer. On the other hand, fancybox is detailed as "JavaScript lightbox library for presenting various types of media". It is a tool that offers a nice and elegant way to add zooming functionality for images, html content and multi-media on your webpages. It is built on the top of the popular JavaScript framework jQuery and is both easy to implement and a snap to customize.

Modernizr and fancybox are primarily classified as "JavaScript Compilers" and "Javascript Utilities & Libraries" tools respectively.

Some of the features offered by Modernizr are:

• Easy to deliver tiered experiences

On the other hand, fancybox provides the following key features:

• Looks great on every device
• Swipe to navigate, spread/pinch to zoom in/out supported on touch devices
• Supports most popular sites as YouTube, Vimeo and Google maps out of the box
