title: Do I need to specify a border-color as a #value and a rgba?
body: <p>I have CSS code that looks like this:</p>
  
  <pre><code>#elementID {
     border-color: #51a351 #51a351 #387038;
     border-color: rgba(0, 0, 0, 0.1) rgba(0, 0, 0, 0.1) rgba(0, 0, 0, 0.25);
  }
  </code></pre>
  
  <p>Can someone please explain. Do I need to specify these as two lines of CSS? I am confused. For example could the green color of the first CSS be part of the second rgba? Also do I really need the rgba. </p>
  
  <p>Sorry if my question is a bit confusing. I took this code from the CSS used in Bootstrap 2.3 from a project I have been asked to tidy up for the very latest browser versions only. </p>
  
  <p>Thanks</p>
