title: Why is there a space between my input boxes?
body: <p>I have a set of input boxes, which I want to be nudged against each other, but for some reason there is a little bit of space between them, despite their container being display block, and there being no margin, padding, or border on the inputs.</p>
  
  <p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
  <div class="snippet-code">
  <pre class="snippet-code-css lang-css prettyprint-override"><code>#container {
    height: 500px;
    background-color: blue;
    display: block;
  }
  
  input {
    width: 30%;
    margin: 0;
    padding: 0;
    border: 0;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div id='container'&gt;
    &lt;input type='number'&gt;
    &lt;input type='number'&gt;
    &lt;input type='number'&gt;
    &lt;input type='number'&gt;
    &lt;input type='number'&gt;
    &lt;input type='number'&gt;
    &lt;input type='number'&gt;
    &lt;input type='number'&gt;
    &lt;input type='number'&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
