title: Change font size and color in php echo
body: <p>I have to change the size and color of the word "PRECIO DIGITAL" and also the price value.
  The php code is this:</p>
  
  <pre><code>add_action( 'woocommerce_single_product_summary', "show_digital_price", 9 );
  function show_digital_price(){
  $precio_digital = get_field('precio_digital');
  if($precio_digital) {
  echo '&lt;b&gt;PRECIO DIGITAL: &lt;/b&gt;';
  echo $precio_digital;
  echo "&lt;br /&gt;";
  }
  }
  </code></pre>
  
  <p>I've tried adding div style like this:</p>
  
  <pre><code>echo '&lt;div style='font-size:1.25em;font-color:#0e3c68'&gt;PRECIO DIGITAL: &lt;/b&gt;';
  </code></pre>
  
  <p>but it doesn't work. Moreover I don't know how to change the size and color of the price itself.</p>
  
  <p>Take a look to the URL where I want to change it (I'd like have it the same font size and color of the normal price): <a href="https://www.editorialufv.es/catalogo/claves-de-seguridad/" rel="nofollow noreferrer">https://www.editorialufv.es/catalogo/claves-de-seguridad/</a></p>
  
  <p>Any solution?</p>
