title: Remove blank spaces between buttons in HTML, CSS
body: <p>I want to remove blank spaces between the buttons, so that when I for example hover over the NORMAL button, there will be no blank space between it and the HARD button. How can I do that and where do these blank spaces come from?</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>body {
    margin: 0;
  }
  #stripe {
      background-color: white;
      text-align: center;
      height: 50px;
      color: black;
  }
  
  button {
      border: none;
      background: none;
      text-transform: uppercase;
      height: 100%;
      font-weight: 700;
      color: black;
      letter-spacing: 1px;
      font-size: inherit;
      transition: all 0.3s;
      outline: none;
  }
  
  button:hover {
      color: white;
      background: black;
  }
  
  .selected {
      color: white;
      background: black;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div id="stripe"&gt;
      &lt;button class="mode"&gt;Easy&lt;/button&gt;
      &lt;button class="mode"&gt;Normal&lt;/button&gt;
      &lt;button class="mode selected"&gt;Hard&lt;/button&gt;
  &lt;/div&gt;</code></pre>
  </div>
  </div>
