Is Skeleton for you?

You should use Skeleton if you’re embarking on a smaller project or just don’t feel like you need all the utility of larger frameworks. Skeleton only styles a handful of standard HTML elements and includes a grid, but that’s often more than enough to get started. In fact, this site is built on Skeleton and has ~200 lines of custom CSS (half of which is the docking navigation).

Love Skeleton and want to Tweet it, share it, or star it? Well, I appreciate that <3

The grid

The grid is a 12-column fluid grid with a max width of 960px, that shrinks with the browser/device at smaller sizes. The max width can be changed with one line of CSS and all columns will resize accordingly. The syntax is simple and it makes coding responsive much easier. Go ahead, resize the browser.

Typography

Type is all set with the rems, so font-sizes and spacial relationships can be responsively sized based on a single <html> font-size property. Out of the box, Skeleton never changes the <html> font-size, but it’s there in case you need it for your project. All measurements are still base 10 though so, an <h1> with 5.0remfont-size just means 50px.

The typography base is Raleway served by Google, set at 15rem (15px) over a 1.6 line height (24px). Other type basics like anchors, strong, emphasis, and underline are all obviously included.

Headings create a family of distinct sizes each with specific letter-spacing, line-height, and margins.

Heading <h1> 50rem

Heading <h2> 42rem

Heading <h3> 36rem

Heading <h4> 30rem

Heading <h5> 24rem
Heading <h6> 15rem

Buttons

Buttons come in two basic flavors in Skeleton. The standard <button> element is plain, whereas the .button-primary button is vibrant and prominent. Button styles are applied to a number of appropriate form elements, but can also be arbitrarily attached to anchors with a .button class.

Forms

Forms are a huge pain, but hopefully these styles make it a bit easier. All inputs, select, and buttons are normalized for a common height cross-browser so inputs can be stacked or placed alongside each other.








Lists
  • Unordered lists have basic styles
  • They use the circle list style

    • Nested lists styled to feel right
    • Can nest either type of list into the other
  • Just more list items mama san
  1. Ordered lists also have basic styles
  2. They use the decimal list style

    • Ordered and unordered can be nested
    • Can nest either type of list into the other
  3. Last list item just for the fun

  • Item 1
  • Item 2
    • Item 2.1
    • Item 2.2
  • Item 3

Code

Code styling is kept basic – just wrap anything in a <code> and it will appear like this. For blocks of code, wrap a <code> with a <pre>.

.some-class {
  background-color: red;
}

.some-class {
  background-color: red;
}

Tables

Be sure to use properly formed table markup with <thead> and <tbody> when building a table.

Media queries

Skeleton uses media queries to serve its scalable grid, but also has a list of queries for convenience of styling your site across devices. The queries are mobile-first, meaning they target min-width. Mobile-first queries are how Skeleton’s grid is built and is the preferrable method of organizing CSS. It means all styles outside of a query apply to all devices, then larger devices are targeted for enhancement. This prevents small devices from having to parse tons of unused CSS. The sizes for the queries are:

  • Desktop HD: 1200px
  • Desktop: 1000px
  • Tablet: 750px
  • Phablet: 550px
  • Mobile: 400px

/* Mobile first queries */

/* Larger than mobile */
@media (min-width: 400px) {}

/* Larger than phablet */
@media (min-width: 550px) {}

/* Larger than tablet */
@media (min-width: 750px) {}

/* Larger than desktop */
@media (min-width: 1000px) {}

/* Larger than Desktop HD */
@media (min-width: 1200px) {}



Utilities

Skeleton has a number of small utility classes that act as easy-to-use helpers. Sometimes it’s better to use a utility class than create a whole new class just to float an element.

/* Utility Classes */

/* Make element full width */
.u-full-width {
  width: 100%;
  box-sizing: border-box; }

/* Make sure elements don't run outside containers (great for images in columns) */
.u-max-full-width {
  max-width: 100%;
  box-sizing: border-box; }

/* Float either direction */
.u-pull-right {
  float: right; }
.u-pull-left {
  float: left; }

/* Clear a float */
.u-cf {
  content: "";
  display: table;
  clear: both; }

Examples


Demo Landing Page

This template is an example of how easy it can be to create a landing page with just the Skeleton grid and a few custom styles. The entire demo is ~150 lines of CSS including comments (most of which is positioning the phones at the top).

More examples will be added to help anyone get started or more familiar with how Skeleton works. The goal is education. If you’re more interested in real, live examples of Skeleton sites, I’ll be creating a “Built on Skeleton” list soon!
