title: How to change the colour of the text of an active button using SASS in Ionic?
body: <p>I am using the SASS method to style my Ionic app.</p>
  
  <p>On can achieve this by modifying the variables stored in sass/_variables.sass.</p>
  
  <p>For a specific button, <strong>I now want to change to color of the text when active (when clicked on)</strong>. However, with the default setup, it is only possible to change the background color of the button when clicked on in the Ionic Setup. For instance, you will find:</p>
  
  <pre><code>$button-light-bg:                 $light !default;
  $button-light-text:               #fff !default;
  $button-light-border:             rgba(255,255,255, 0) !default;
  $button-light-active-bg:          $light !default;
  $button-light-active-border:      $light !default;
  </code></pre>
  
  <p>How do I add an additional variable in Ionic to change the text color to black? For instance:</p>
  
  <pre><code>$button-light-active-text:        #000 !default; // does not work
  </code></pre>
  
  <p>Now, this button needs to be used somewhere? Where in the Ionic Library can I modify this?</p>
