MixItUp is a CSS3/jQuery-powered filter & sort plugin.

MixItUp orders filtered and sorted plugins with animated motions. It’s great for fluid and responsive layouts, such as those for blogs, portfolios, galleries and more — the developers have even created a playing card demo.

It’s well documented and the website of the plugin does well to showcase the different things you can do with this plugin.

The sole drawback is — you guessed it — browser support: only modern browsers and IE10 are supported at the moment.

jQuery has gotten richer in features throughout the years — but it’s also gotten bigger and can contain many features a developer won’t want to use.

jQuery Builder helps making a custom build of jQuery, allowing developers to choose which modules to include or not.

The builder is also available for the Node.js command line tool. This is a very nice way of reducing the load time for your websites.

JSDares is a website which offers learning important JavaScript concepts through creating games.

JSDares was created by Jan Paul Posma and – interestingly enough – by the University of Oxford.

JSDares has a number of cool dares to try and this might make for a very fun way of brushing up your JavaScript or starting to learn it.

Bootstrap Magic is a theme generator for Bootstrap. It has a live preview which updates in real-time.

Bootstrap Magic supports LESS and all of its functions. The output is a minified (or not) CSS file which you can use for your very own hand-built Bootstrap design.

Gallery CSS is a CSS-powered image gallery that doesn’t use any scripts.

Gallery is available in both prefixed and unprefixed versions. Gallery uses a ton of modern features that allow it to run on pure CSS.

While this image gallery is free, the developer is selling an optional screen cast for $12, which is pretty much mandatory given the slim documentation.

JavaScript Patterns is a JS pattern collection that features common patterns for all things JavaScript.

The set of patterns includes object, function, plugin, design, code reuse and other patterns.

The website is being updated regularly and you can follow new updates via Twitter.
