title: Subscribe form implementation in Bootstrap
body: <p>I'm currently involved in the project, where it is needed to implement the subscription option for Bootstrap.<br>
  Currently I have the following code:</p>
  
  <pre><code>&lt;center&gt;
   &lt;form class="form-inline" role="form"&gt;
     &lt;div class="form-group"&gt;
      &lt;label class="sr-only" for="exampleInputEmail2"&gt;Email address&lt;/label&gt;
      &lt;input type="email" class="form-control transparent" placeholder="Enter your email"&gt;
     &lt;/div&gt;
    &lt;button type="submit" class="btn btn-success btn-fill"&gt;Subscribe&lt;/button&gt;
   &lt;/form&gt;
  &lt;/center&gt;
  </code></pre>
  
  <p>How can I make the "Subscribe" button to link to an email? Basically, how can find out if somebody had subscribed to the newsletter?</p>
