Usage

Skeletons can be quickly added to any project with a few simple lines of code.

Headers

Apply the skeleton class to any type of header and it will automatically adjust to the font-size of the header stylings:

<h1 class="skeleton"></h1>
<h2 class="skeleton"></h2>
<h3 class="skeleton"></h3>
<h4 class="skeleton"></h4>
<h5 class="skeleton"></h5>
<h6 class="skeleton"></h6>

Paragraphs

You can create paragraph skeletons by applying the skeleton class to the paragraph tag, then including however many span tags you'd like with the skeleton__line class within the paragraph. In order to make the paragraph skeleton look more like a paragraph, the last line is set to 50% width.

<div>
  <p class="skeleton">
    <span class="skeleton__line"></span>
    <span class="skeleton__line"></span>
    <span class="skeleton__line"></span>
    <span class="skeleton__line"></span>
  </p>
</div>

Line Width

You can adjust the line width by applying a size modifier class:

Width	Modifier Class
Small, 25%	.skeleton--sm
Medium, 50%	.skeleton--md
Large, 75%	.skeleton--lg
Full, 100%	.skeleton--full

<h1 class="skeleton skeleton--sm"></h1>
<h1 class="skeleton skeleton--md"></h1>
<h1 class="skeleton skeleton--lg"></h1>
<h1 class="skeleton skeleton--full"></h1>

Alignment

You can text align the skeleton using alignment modifier classes:

Alignment	Modifier Class
Left	.skeleton--left
Center	.skeleton--center
Right	.skeleton--right

<!-- Left Align -->
<p class="skeleton skeleton--left">
  <span class="skeleton__line"></span>
  <span class="skeleton__line"></span>
  <span class="skeleton__line"></span>
  <span class="skeleton__line"></span>
</p>

<!-- Center Align -->
<p class="skeleton skeleton--center">
  <span class="skeleton__line"></span>
  <span class="skeleton__line"></span>
  <span class="skeleton__line"></span>
  <span class="skeleton__line"></span>
</p>

<!-- Right Align -->
<p class="skeleton skeleton--right">
  <span class="skeleton__line"></span>
  <span class="skeleton__line"></span>
  <span class="skeleton__line"></span>
  <span class="skeleton__line"></span>
</p>

Images

You can create an image skeleton by adding the .skeleton-image class to an img tag -- do not include the src attribute. By default this will apply the image skeleton at 100% height and width of the parent container.

Sizes

Here are some default sizes we have included for skeleton images:

Size	Modifier Class
Small, 50x50	.skeleton-image--sm
Medium, 100x100	.skeleton-image--md
Large, 200x200	.skeleton-image--lg
X-Large, 400x400	.skeleton-image--xl
Full, 100% x 100%	.skeleton-image--full

<img class="skeleton-image skeleton-image--md" />
<img class="skeleton-image skeleton-image--sm" />
<img class="skeleton-image skeleton-image--lg" />
<img class="skeleton-image skeleton-image--xl" />

Shapes

You can also make different image shapes using shape modifier classes:

Shape	Description	Modifier Class
Landscape Rectangle	Sets the width of the image to 100%	.skeleton-image--landscape
Portrait Rectangle	Sets the height of the image to 100%	.skeleton-image--portrait
Circle	Sets the border radius to 50%	.skeleton-image--circle

<img class="skeleton-image skeleton-image--lg skeleton-image--landscape" />
<img class="skeleton-image skeleton-image--lg skeleton-image--portrait" />
<img class="skeleton-image skeleton-image--lg skeleton-image--circle" />

Animation

To add animation, add a span.skeleton--animation within the .skeleton__line elements in headers or paragaphs.

<div>
  <p class="skeleton">
    <span class="skeleton__line">
      <span class="skeleton--animation"></span>
    </span>
        <span class="skeleton__line">
      <span class="skeleton--animation"></span>
    </span>
    <span class="skeleton__line">
      <span class="skeleton--animation"></span>
    </span>
    <span class="skeleton__line">
      <span class="skeleton--animation"></span>
    </span>
  </p>
</div>

JavaScript Utility

The easiest and our preferred way to add Skeletons is by using the included JavaScript utilities.

On either a header tag or a paragraph tag, add the skeleton class and a data-lines attribute with the number of lines you'd like the skeleton to have:

<h2 class="skeleton skeleton--md" data-lines="2"></h2>
<p class="skeleton" data-lines="7"></p>

You can also give the skeleton animation by adding the data-animation attribute and setting it to true:

<h2 class="skeleton skeleton--md" data-animation="true"></h2>
<p class="skeleton" data-lines="7" data-animation="true"></p>
