title: How to remove banding of gradient background
body: <p>I'm training a little bit of CSS with repl.it and I decided to put a gradient background, but it is giving this error:</p>
  <p><a href="https://i.stack.imgur.com/kGFdM.png" rel="nofollow noreferrer">https://i.stack.imgur.com/kGFdM.png</a></p>
  <p>I'm using the following code:</p>
  <pre><code>body {background: linear-gradient(to bottom, #17748b, #003a8b)}
  </code></pre>
  <p>it was supposed to be an easy thing, but i am not managing to solve this at all.</p>
