Don't forget to check out my new article about this plugin on the Smashing Magazine.
You can choose to include only the features that you need using the online build tool or by compiling it yourself with Grunt.js. Size of core JS file is about 3KB + each module weighs about 0.5KB (gzipped). Sass CSS preprocessor is used for easier skinning, but you're not obligated to use it.
The majority of lightbox plugins require you to define size of it via JS option. Magnific Popup does not - feel free to use relative units like EM's or resize lightbox with help of CSS media queries. Update content inside lightbox without worrying about how it'll resize and center.
Magnific Popup displays images before they're completely loaded to take full advantage of progressive loading. For in and out transitions CSS3 is used instead of slow JavaScript animation.
Default controls are made with pure CSS, without external graphics. For the main image there is a built in way to provide appropriate source for different pixel density displays.
Plugin has an option to automatically switch to alternative mobile-friendly source on small screen size. Brad Frost has a terrific article about this technique.
Popup has an extendable micro templating engine that reuses existing DOM elements (example), which is especially useful when your popups same pattern.
Tested on desktop: Chrome, Safari, FF, Opera, IE8+, partial support of IE7 (works, but some visual layout features, like vertical centering, are missing). Mobile: default browser in Android 2.3+, iOS5+, Blackberry 10+, WP7+, mobile Opera and Chrome on Android. If you noticed any bug, please open an issue on GitHub
Script is available under MIT license and will always be kept this way.
But please do me a favor and do not create a public WordPress plugin based on it, because I will make it soon and it will be open souce too. (Want to get notified?).
Please report bugs via GitHub and ask general questions through StackOverflow. Feel free to submit commit, even the tiniest contributions to the script or to the documentation are very welcome.
