Add External Stylesheets/Pens

Any URL's added here will be added as <link>s in order, and before the CSS in the editor. If you link to another Pen, it will include the CSS from that Pen. If the preprocessor matches, it will attempt to combine them before processing.

+ add another resource

You're using npm packages, so we've auto-selected Babel for you here, which we require to process imports and make it all work. If you need to use a different JavaScript preprocessor, remove the packages in the npm tab.

Add External Scripts/Pens

Any URL's added here will be added as <script>s in order, and run before the JavaScript in the editor. You can use the URL of any other Pen and it will include the JavaScript from that Pen.

Use npm Packages

We can make npm packages available for you to use in your JavaScript. We use webpack to prepare them and make them available to import. We'll also process your JavaScript with Babel.

⚠️ This feature can only be used by logged in users.

  Topcoat Button Bar
</h1>
<p>
  Default style for Topcoat Button Bar.
  <br>
  Requirements are portable and accessible markup with flexible and performant css. 
  <br>
  No javascript required
</p>

<h2>Normal Button Bar</h2>

<div class="topcoat-button-bar">
   <div class="topcoat-button-bar__item">
     <button class="topcoat-button-bar__button">One</button>
   </div>
   <div class="topcoat-button-bar__item">
     <button class="topcoat-button-bar__button">Two</button>
   </div>
   <div class="topcoat-button-bar__item">
     <button class="topcoat-button-bar__button">Three</button>
   </div>
</div>

<h2>Select Button Bar</h2>

<div class="topcoat-button-bar">
   <label class="topcoat-button-bar__item">
     <input type="radio" name="topcoat">
     <button class="topcoat-button-bar__button">One</button>
   </label>
   <label class="topcoat-button-bar__item">
     <input type="radio" name="topcoat">
     <button class="topcoat-button-bar__button">Two</button>
   </label>
   <label class="topcoat-button-bar__item">

<h2>Toggle Button Bar</h2>

<div class="topcoat-button-bar">
   <label class="topcoat-button-bar__item">
     <input type="checkbox">
     <button class="topcoat-button-bar__button">One</button>
   </label>
   <label class="topcoat-button-bar__item">

   </label>
</div>
     
<div class="spacer">

</div>

<h2>Accessibility</h2>
<p>
  The stateful button bars use inputs and the :checked pseudo style to add functionality without needing Javascript.
</p>
<p>
  These stateful button bars rely on implicit ( or nested ) input labels instead of each needing an `id` and a matching `for` attribute on the corresponding label. This makes them more portable since each `id` on a page needs to be unique.
</p>
<p>
  If you need to support legacy browsers and accessibility devices you can easily support these by adding the `id` and `for` attributes.
</p>
  
<div class="topcoat-button-bar">
   <label for="one" class="topcoat-button-bar__item">
     <input id="one" type="radio" name="topcoat">
     <button class="topcoat-button-bar__button">One</button>
   </label>
   <label for="two" class="topcoat-button-bar__item">
     <input id="two" type="radio" name="topcoat">
     <button class="topcoat-button-bar__button">Two</button>
   </label>
   <label for="three" class="topcoat-button-bar__item">
     <input id="three" type="radio" name="topcoat">
     <button class="topcoat-button-bar__button">Three</button>

<h2>Semantic variations</h2>
<p>
  This is where the CSS classes start to show their true benefit. You can use different semantic mark up to reflect your specific use case while maintiaing the same CSS classes.
</p>
<p>
  If you are using this button bar as your primary navigation you could change the markup to reflect this semantically by using a nav element. Component looks the same with different mark up.
</p>

<nav class="topcoat-button-bar">
   <div class="topcoat-button-bar__item">
     <button class="topcoat-button-bar__button">One</button>
   </div>
   <div class="topcoat-button-bar__item">
     <button class="topcoat-button-bar__button">Two</button>
   </div>
   <div class="topcoat-button-bar__item">
     <button class="topcoat-button-bar__button">Three</button>
   </div>
</nav>
<p>
  *look at HTML source
</p>
<p>
  If you are using this button bar as a list of links you could change the markup to semantically reflect this by using an unorderd list with anchor tags. Again, component looks the same with different mark up.
</p>
  
<ul class="topcoat-button-bar">
   <li class="topcoat-button-bar__item">
     <a href="http://topcoat.io"
        target="_blank" 
        class="topcoat-button-bar__button">
       Topcoat
     </a>
   </li>
   <li class="topcoat-button-bar__item">
     <a href="http://brackets.io" 
        target="_blank" 
        class="topcoat-button-bar__button">
       Brackets
     </a>
   </li>
   <li class="topcoat-button-bar__item">
     <a href="http://html.adobe.com" 
        target="_blank" 
        class="topcoat-button-bar__button">

     </a>
   </li>
</ul>

<h2>Adding sizing</h2>

<p>
  Topcoat separates layout and positioning from styling to make the components more reusable. 
  <br>
  The below example has the layout class `full` added to elements to show how sizing can be applied.
</p>
  
<div class="topcoat-button-bar full">
   <div class="topcoat-button-bar__item">
     <button class="topcoat-button-bar__button full">One</button>
   </div>
   <div class="topcoat-button-bar__item">
     <button class="topcoat-button-bar__button full">Two</button>
   </div>
   <div class="topcoat-button-bar__item">
     <button class="topcoat-button-bar__button full">Three</button>
   </div>
</div>
