title: How to share the current page with the Facebook,LinkedIn and Twitter Share Button?
body: <p>I'm sorry if this question has already been asked but this case is different. I'm trying to make a Facebook button that is sharing the current URL but I have no idea how to do this.My question is : What should I put instead of 'homepage' so that these buttons share the page the user is currently on instead of a specific URL ?
  Here's what the current code looks like (I replaced the website's URL by homepage) :</p>
  
  <pre><code>  &lt;a href="http://www.facebook.com/sharer.php?u='homepage' target="_blank" style="text-decoration:none"&gt;
      &lt;img src="http://image.noelshack.com/fichiers/2015/25/1434621881-iconmonstr-facebook-4-icon-32.png" alt="Facebook"&gt;
  &lt;/a&gt;
  
  &lt;!-- LinkedIn --&gt;
  &lt;a href="http://www.linkedin.com/shareArticle?mini=true&amp;amp;url=homepage" target="_blank" style="text-decoration:none"&gt;
      &lt;img src="http://image.noelshack.com/fichiers/2015/25/1434621881-iconmonstr-linkedin-4-icon-32.png" alt="LinkedIn"&gt;
  &lt;/a&gt;
  
  &lt;!-- Twitter --&gt;
  &lt;a href="https://twitter.com/share?url=homepage" target="_blank" style="text-decoration:none"&gt;
      &lt;img src="http://image.noelshack.com/fichiers/2015/25/1434621881-iconmonstr-twitter-4-icon-32.png" alt="Twitter"&gt;
  &lt;/a&gt;
