title: Center form in bootstrap
body: <p>I am having issues centering a form in Bootstrap. I also don't seem to be able to resize the input boxes. I would like to have it centered.</p>
  
  <p>This is what I have:</p>
  
  <pre><code>     &lt;div class="form-group row" id="SignupCreate"&gt;
        &lt;div class="col-sm-4"&gt;
      &lt;label&gt;Email&lt;/label&gt;
        &lt;input type="email" class="form-control" id="inputEmail" placeholder="Email"&gt;
      &lt;/div&gt;
  
        &lt;div class="col-sm-4"&gt;
      &lt;label&gt;Password&lt;/label&gt;
        &lt;input type="password" class="form-control" id="inputPassword" placeholder="Password"&gt;
    &lt;div class="col-sm-4"&gt;
        &lt;button type="submit"&gt;Submit&lt;/button&gt;
    &lt;/div&gt;
      &lt;/div&gt;
      &lt;/div&gt;
  </code></pre>
  
  <p>And for CSS I started:</p>
  
  <pre><code>#SignUpCreate {
      padding-top: 200px;
      margin-right: 30px;
      margin-left: 30px;
  
  }
  </code></pre>
