title: What is the difference between Use Font-awesome all.js and all.css?
body: <p>I have to use font awesome in my Web, and I found that I have 2 ways to implements Font Awesome.</p>
  <p>I want to work with 5.0.1 version, I realized that using ALL.CSS allows me to use Font-awesome in classes with: AFTER in CSS, but beyond that I do not know what the difference is, and what each one is used for, and another question, when I should use both.</p>
  <pre><code>&lt;link href=&quot;https://use.fontawesome.com/releases/v5.0.1/css/all.css&quot; rel=&quot;stylesheet&quot;&gt;
  
  &lt;script defer src=&quot;https://use.fontawesome.com/releases/v5.0.1/js/all.js&quot;&gt;&lt;/script&gt;
  </code></pre>
  <p>I hope to use the lightest font-awesome to implement</p>
