title: Is there any way to change box shadow without passing a color?
body: <p>Here is my issue. I have 2 css classes, my elements can have either</p>
  
  <pre><code>.classA{box-shadow:inset -2px 0px 0px 0px rgba(63,191,31,1);}
  .classB{box-shadow:inset -2px 0px 0px 0px rgba(204,29,29,1);}
  </code></pre>
  
  <p>I wish to use a third class to change the inset but not the color</p>
  
  <pre><code>.classC{box-shadow:inset -10px 0px 0px 0px;}
  </code></pre>
  
  <p>That works (the shadow is here) but the color turns black. I would like to keep my original color.</p>
  
  <p>How to change the shadow properties using <strong>CSS ONLY</strong> without losing the color?</p>
