 * I would like to implement function to .site-title .
    I expect it will change 
   color dynamically.
 * What is a proper way to call function and apply that to class=”site-title”
    `
   randomColor(); // Returned a random color as a hex string`
 * to call [java-script](https://raw.githubusercontent.com/davidmerfield/randomColor/master/randomColor.js)
   function

 * This should work. Try adding to a post or page to test:
 *     ```
       <script>
       jQuery(document).ready(function($) {
         r = Math.floor(Math.random() * (256));
         g = Math.floor(Math.random() * (256));
         b = Math.floor(Math.random() * (256));
         $('#site-title a').css('color', 'rgb('+r+','+g+','+b+')' );
       });
       </script>
       ```
   
 * This works if your theme implements the site-title as a an ID, so if your theme
   has it as a class you’ll need to update your CSS selector as necessary.
 * Also, once you have this working you should add it to a JS file and enqueue it
   if you want it to apply to all pages.
