title: Jquery - Change span text color based on numeric value
body: <p>I'm trying to build a review system in WP with Advanced Custom Fields, but I can't solve this. I want to change the color of a score based on the number. 
  For example: if the writer puts 0-40 as score it has to be changed to red; if the writer puts 40-60 it has to be changed to orange; if the writter puts 60-80 it has to be green...</p>
  
  <p>HTML:</p>
  
  <pre><code>&lt;div class="r-summary"&gt;
     &lt;span id="score"&gt;
        &lt;?php the_field('score'); ?&gt; */HERE GOES THE NUMBER WITH THE SCORE
     &lt;/span&gt;
   &lt;/div&gt;
  </code></pre>
