title: Set CSS width to 100% + right border is missing?
body: <p>I set a div's width to 100% of the window. When I apply a border to this div, the right border is cut off. Do I have to perform a box model hack to this? </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>#textBoxContainer {
    width:100%;
    height:30%;
    position:fixed;
    z-index:99;
    bottom:0px;
    left:0px;
    background-color:#999;
    border: 4px solid #000;
  }</code></pre>
  <pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;div id="textBoxContainer"&gt;&lt;/div&gt;</code></pre>
  </div>
  </div>
  </p>
