            Inspired on this site <a href="http://randomstringtocsscolor.com" target="_blank">randomstringtocsscolor.com</a>
          </p>
          <p>
            I decided to use a different way to calculate the colors. I use CRC-32 (<a href="https://en.wikipedia.org/wiki/Cyclic_redundancy_check" target="_blank">Cyclic Redundancy Check</a>) to convert the text into 32 bits. Using this  <a href="http://www.simplycalc.com/crc32-source.php" target="_blank">http://www.simplycalc.com/crc32-source.php</a> as the algorithm. Two different colors are created by the text, then a linear gradient is created with those colors.

          <h2>How does it work?</h2>
          <ul class="list-unstyled">
            <li>Take the text and run it through the CRC algorithm</li>
            <li>Split result into 4 numbers (1 byte each)</li>
            <li>The first 3 bytes are used as the RGB colors. Each byte ranges from 0 - 255. The last byte is used to calculate a percentage of 255. This percentage is the alpha in the color. </li>
