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 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.

  <h1>Text Contrast Issues That Cannot Be Detected with Automated Tools</h1>

  <p>
    These are based on real-world examples that we have encountered in audits, though this is simplified to show the salient bits.
  </p>

  <h2>Text on a Background Gradient</h2>

  <p>
    Pretend this is one "slide" from a carousel, which is where I see this crop up most frequently.
  </p>

  <div>
    <p>
      This is some sort of marketing text, usually justifying some sort of call to action following.
      <a href="#">Call to Action!</a>
    </p>
  </div>

  <h2>Text on a Background Texture</h2>

  <p>
    This is a CSS background texture. While the colors are at least embedded in the code, where they may fall below the text is impossible to determine
  </p>

  <div>
    <p>
      This is some sort of marketing text, usually justifying some sort of call to action following.
      <a href="#">Call to Action!</a>
    </p>
  </div>

  <h2>Text on a Background Image</h2>

  <p>
    In responsive layouts in particular it can be very hard to identify where an image will sit below the text.
  </p>

  <div>
    <p>
      This is some sort of marketing text, usually justifying some sort of call to action following.
      <a href="#">Call to Action!</a>
    </p>
  </div>

  <h2>Text on an Animated Background Image</h2>

  <p>
    This is a CSS animation, but an animated GIF can be just as hard to map to the text with an automated tool.
  </p>

  <div>
    <p>
      This is some sort of marketing text, usually justifying some sort of call to action following.
      <a href="#">Call to Action!</a>
    </p>
  </div>

  <h2>Text on an Animated Background Texture</h2>

  <p>
    Same as above, but with CSS only.
  </p>

  <div>
    <p>
      This is some sort of marketing text, usually justifying some sort of call to action following.
      <a href="#">Call to Action!</a>
    </p>
  </div>

  <h2>Text Absolutely Positioned over a Box</h2>

  <p>
    In this case the text is not in a container. Oh. Nope. This one was flagged. Good job, tool.
  </p>

  <div>
  </div>
  <p>
    This is some sort of marketing text, usually justifying some sort of call to action following.
    <a href="#">Call to Action!</a>
