title: Does linking to JQuery CDN slow my site down?
body: <p>A total newbie. This seems like a basic question, but one that I can't find the answer to:</p>
  
  <p>I have a few lines of JQuery to show and hide a responsive menu on half-a-dozen pages. I understand I need to "link" to the JQ library:</p>
  
  <pre><code> &lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>Will this slow my site down? Will a visitor have to download the whole JQ library for my two lines of code to work? if this is the case I might revert back to Javascript.</p>
