title: How to lighten / darken a linear gradient properly?
body: <p>I'm trying to lighten / darken my button background when <code>:hover</code> on.</p>
  <p>I tried different style like</p>
  <pre><code>  background-color:rgba(0,0,0,0.5);
    background-blend-mode:darken;
  </code></pre>
  <p>But it doesn't work like i want.
  I want a really really light lighten and same for the darken.</p>
  <pre><code> background: linear-gradient(173deg, rgba(255,121,218,1) 0%, rgba(214,108,219,1) 39%, rgba(171,94,220,1) 85%, rgba(155,89,220,1) 100%);     
  </code></pre>
