Pure CSS One Page Scroll Effect

Preview:

Description:

A pure HTML/CSS solution to create a smooth, fullscreen one page scroll effect for your single page web application. Based on CSS3 and radio & label hacks. Allows the user to navigate between pages with side navigation and/or arrow keys.

How to use it:

Insert the sectioned content into the ‘label’ elements and then wrap them together with the ‘radio input’ based navigation into a container called ‘container’ like this:

<div class="container">
  <form>
    <input type="radio" id="Slide1" name="slider" title="Home"  checked="checked"/>
    <input type="radio" id="Slide2" name="slider" title="Section 2"/>
    <input type="radio" id="Slide3" name="slider" title="Section 3"/>
    <input type="radio" id="Slide4" name="slider" title="Section 4"/>
    <input type="radio" id="Slide5" name="slider" title="Section 5"/>
    <div class="labels">
      <label for="Slide1" id="Slide1" class="Slide">
        <div class="content">
          <h1><strong>Pure CSS</strong> one page vertical navigation</h1>
        </div>
      </label>
      <label for="Slide2" id="Slide2" class="Slide">
        <div class="content">
          <h2>Section 2</h2>
        </div>
      </label>
      <label for="Slide3" id="Slide3" class="Slide">
        <div class="content">
          <h2>Section 3</h2>  
        </div>
      </label>
      <label for="Slide4" id="Slide4" class="Slide">
        <div class="content">
          <h2>Section 4</h2>
        </div>
      </label>
    </div>
  </form>
</div>
