Styleguide is a tool to make creating and maintaining styleguides easy. All you need to do is to add the Styleguide to a separate folder in your project. Use it as your CSS. You just need to import the generated file inside your HTML and you are all set! This way the Styleguide will be synced with your project. Isn’t that awesome!?
Just copy your project’s CSS and paste it in the Styleguide CSS file. Now you only need to customize the modules to use the proper classes. You can always create/edit any module when you need. The Styleguide is also a independent project. You can download it and use it in your browser. Then all you need to do is edit it’s CSS and set/customize the modules. When you are finished you can send the files to a server or use the HTML version.

Image Blur Plugin is an Ultra small plugin (4kb minified, 1.5kb gzipped) for Blurring images. This plugin utilizes SVG filter to blur the image if SVG is supported by the browser (all except IE), otherwise the plugin creates an IMG tag and applies a special IE-only filter in CSS. If you are using Velocity.js animation library, the plugin will automatically detect its presence and make fade in/fade out animations more performant, especially on mobile. If Velocity is not present on the page, jQuery’s “animate” is used.

Requirements: JavaScript Framework

Codyhouse has put together a set of Page Scroll Effects, they are some fancy effects that take place while the user is surfing through the sections of a web page. Some of the effects are quite extreme, but they can prove very useful if your goal is to create an immersive user experience. All animations have been created using Velocity.js.
Please note that these effects are not visible on small devices, where the user can simply scroll through the list of sections. They have tested the effects on mobile and performance was poor, therefore they decided to limit them to bigger and more powerful devices.

Requirements: JavaScript Framework

As of today anyone can set up an account and start prototyping in seconds. Atomic approaches prototyping in the way designers think: design your different states as separate pages, then create automatic animations between them.
Create your designs from scratch in Atomic, or bring your assets in from another drawing tool. Draw Hotspots over elements in your design and link pages together into a prototype. You can choose to animate these transitions between pages. When the same object exists on both pages, Atomic will animate any changes automatically. These connections between objects are created when you copy-and-paste them from one page to another, or when you duplicate a page. Anything that only exists on one page will be faded in or out. Happy prototyping.
