A Beautiful Boilerplate for Responsive, Mobile-Friendly Development
- Tweet --
What Is It?
-Skeleton is a small collection of CSS & JS files that can help you rapidly develop sites that look beautiful at any size, be it a 17" laptop screen or an iPhone. Skeleton is built on three core principles:
-
- Responsive Grid Down To Mobile
-Skeleton has a familiar, lightweight 960 grid as its base, but elegantly scales down to downsized browser windows, tablets, mobile phones (in landscape and portrait). Go ahead, resize this page!
-
- Fast to Start
-Skeleton is a tool for rapid development. Get started fast with CSS best practices, a well-structured grid that makes mobile consideration easy, an organized file structure and super basic UI elements like lightly styled forms, buttons, tabs and more.
-
- Style Agnostic
-Skeleton is not a UI framework. It's a development kit that provides the most basic styles as a foundation, but is ready to adopt whatever your design or style is.

The Grid
-Skeleton's base grid is a variation of the 960 grid system. The syntax is simple and it's effective cross browser, but the awesome part is that it also has the flexibility to go mobile like a champ. Go ahead, resize the browser and watch as the layout reacts!
--
Typography
-The typography of Skeleton is designed to create a strong hierarchy with basic styles. The primary font is the classic Helvetica Neue, but the font stack can be easily changed with just a couple adjustments. Regular paragraphs are set at a 14px base with 21px line height.
-Heading <h1>
-Heading <h2>
-Heading <h3>
-Heading <h4>
-Heading <h5>
-Heading <h6>
---This is a blockquote style example. It stands out, but is awesome

Buttons
-Buttons are intended for action and thus should have appropriate weight. The standard button is given that weight with a little bit of depth and a strong hover.
- Click Me For Action --
Tabs
-Some very simple tabs that have dead simple jQuery that hook them up to their corresponding content.
--
-
- Simple -
- Lightweight -
- Mobile -
-
-
- The tabs are clean and simple unordered-list markup and basic CSS. -
- The tabs are cross-browser, but don't need a ton of hacky CSS or markup. -
- The tabs work like a charm even on mobile devices. If there are too many they will stack (it's not completely awesome, but still retains functionality). -
-
Forms
-Forms can be one of the biggest pains for web developers, but just use these dead simple styles and you should be good to go.

-
Media Queries
-Skeleton uses a lot of media queries to serve the scalable grid, but also for the convenience of styling your site on different size screens. Skeleton's media queries are almost exclusively targeted at max and min widths rather than device sizes or orientations. The advantage of this is browsers and future mobile devices that don't map to exact set dimensions will still benefit from the styles. That being said, all of the queries were written to be optimal on Apple iOS devices. The built in media queries include:
--
-
- Smaller than 960: Smaller than the standard base grid -
- Tablet Portrait: Between 768px and 959px -
- All Mobile Sizes: Less than 767px -
- Just Mobile Landscape: Between 480px and 767px -
- Just Mobile Portrait: Less than 479px -

Skeleton has been tested across as many devices and browsers as I could get my hands on:
--
-
- Latest Chrome (Mac/PC) -
- Firefox 4.0, 3.6, 3.5, 3.0 (Mac/PC) -
- Latest Safari -
- IE9, IE8, IE7 -
- iPhone (Retina) -
- Droid (Charge/Original) -
- iPad -
There is a small hiccup though - older non-CSS3 browsers aren't going to respond to the media-queries and thus will be served the standard 960 grid even if they are resized. In the spirit of graceful degradation though, I'm going to let this be instead of trying to implement a JS solution. If you are interested in one though, try the respond.js polyfill.
-Notes on IE: We all know sometimes IE doesn't behave, so through the genius of conditional CSS I've added a class of "ie" to all versions of the browser, as well as specific targets for each (i.e. "ie6", "ie7", "ie8"). It's not a perfect world, but hopefully this will help make naughty IE behave.

-More importantly, I would love to have a small community of contributors to Skeleton, so please feel free to jump over the Skeleton Github page and contribute to make Skeleton a better boilerplate for everyone! I would also love to know if you built a site on Skeleton - I'm planning on tying a gallery into these docs, so just shoot me the URL at hi@getskeleton.com
