title: Remove the space between checkboxes
body: <p>I have a form which contains several checkboxes align vertically in a div. I want to remove the space between each checkbox. But I can't find any solutions.</p>
  
  <pre><code>&lt;div style="height:100px;width:25px;float:left;"&gt;
    &lt;input type="checkbox"/&gt;
    &lt;input type="checkbox"/&gt;
    &lt;input type="checkbox"/&gt;
    &lt;input type="checkbox"/&gt;
    &lt;input type="checkbox"/&gt;
    &lt;input type="checkbox"/&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>Does anyone have any solution to this problem?</p>
