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.

JavaScript

Babel is required to process package imports. If you need a different preprocessor remove all packages first.

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.

        <h3>CSS Only Material Design Button Ripple Effect</h3>
        <p>I was looking at the Google Material Design stuff and wanted to see if I could approximate the click ripple effect using CSS only.<br />The requirements I had:</p>
        <ul>
          <li>CSS only</li>
          <li>No extra HTML elements</li>
          <li>No extra Javascript</li>
        </ul>
        <p>The result:</p>
        <div>
          <button class="button-base ripple">Ripple Button</button>
          <button class="button-base ripple">Ripple Button</button>
          <button class="button-base ripple">Ripple Button</button>
        <div>
        <p>Problems:</p>
        <ul>
          <li>To size and position the ripple, I had to use absolute fixed sizes and positioning, <br />so the scale and timing would be off if the element is much larger than a button</li>
          <li>No Javascript, so can't position the ripple at the click origin</li>
          <li>Browser compatibility? ¯\_(ツ)_/¯</li>
          <li>The click uses :focus, so it's only going through once</li>
        </ul>
    </div>
</div>
