The demo uses a simple set of <code>radio</code> inputs that correspond to their own individual <code>slide</code> element. The framework looks at the currently <code>checked</code> input, then changes the <code>opacity</code> and <code>z-index</code> of its corresponding slide item. Pretty straightforward stuff!</p> -<p>Let's break down each piece:</p> -<h2>The HTML</h2> -<pre><code><div class="slider"> - <input type="radio" name="pagination" value="1" checked> - <input type="radio" name="pagination" value="2"> - <input type="radio" name="pagination" value="3"> - <input type="radio" name="pagination" value="4"> - <input type="radio" name="pagination" value="5"> - - <div class="slide"> - <h2>Slide 1</h2> - </div> - <div class="slide"> - <h2>Slide 2</h2> - </div> - <div class="slide"> - <h2>Slide 3</h2> - </div> - <div class="slide"> - <h2>Slide 4</h2> - </div> - <div class="slide"> - <h2>Slide 5</h2> - </div> -</div> + +<p>Let’s break down each piece:</p> + +<h2 id="the-html">The HTML</h2> + +<pre><code><div class="slider"> + <input type="radio" name="pagination" value="1" checked> + <input type="radio" name="pagination" value="2"> + <input type="radio" name="pagination" value="3"> + <input type="radio" name="pagination" value="4"> + <input type="radio" name="pagination" value="5"> + + <div class="slide"> + <h2>Slide 1</h2> + </div> + <div class="slide"> + <h2>Slide 2</h2> + </div> + <div class="slide"> + <h2>Slide 3</h2> + </div> + <div class="slide"> + <h2>Slide 4</h2> + </div> + <div class="slide"> + <h2>Slide 5</h2> + </div> +</div> </code></pre> -<p>There isn't a whole lot going on here.
