title: Internal CSS works, but external doesn't
body: <p><strong>Internal CSS works, but external doesn't. I've tried the external with the code !important, but it just didn't made any sense.</strong>
  I want to add a gallery to my site. But I have a problem. As I've seen in the browser some margin overwrites the ext. CSS. But here's the thing, I have no margins in the HTML code. The only thing I can imagine is that the Bootstrap is doing something with high priority.<br></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>div.gallery {
      margin: 5px;
      border: 1px solid #ccc;
      width: 180px;
      position: static;
  }
        
  div.gallery:hover {
      border: 1px solid #777;
  }
        
  div.gallery img {
      width: 100%;
      height: auto;
  }
        
  div.desc {
      padding: 15px;
      text-align: center;
  }</code></pre>
