body: <p>Im working with this bootstrap html file as the following:</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-html lang-html prettyprint-override"><code>&lt;head&gt;
  
      &lt;title&gt;Bootstrap Example&lt;/title&gt;
      &lt;meta charset="utf-8"&gt;
      &lt;meta name="viewport" content="width=device-width, initial-scale=1"&gt;
  
      &lt;link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"&gt;
      &lt;link rel="stylesheet" href="https://www.w3schools.com/w3css/4/w3.css"&gt;
  
  &lt;/head&gt;
  
  &lt;body&gt;
  
      &lt;div class="w3-sidebar w3-bar-block" style="width:35%"&gt;
          &lt;h2 style="margin-left:15px;"&gt;Some Favorites&lt;/h2&gt;
          &lt;a href="#" class="w3-bar-item w3-button" style="color:blue;"&gt;Celery Root&lt;/a&gt;
          &lt;a href="#" class="w3-bar-item w3-button" style="color:blue;"&gt;Spaghetti Squash&lt;/a&gt;
          &lt;a href="#" class="w3-bar-item w3-button" style="color:blue;"&gt;Killer Mushroom&lt;/a&gt;
          &lt;input type="text" class="form-control" style="margin-left: 15px;"&gt;
          &lt;button type="button" class="btn btn-primary" style="margin-left:15px; width: 230px; height:50px; font-size: 20px;"&gt;Search Recipes&lt;/button&gt;
      &lt;/div&gt;
  
      &lt;script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"&gt;&lt;/script&gt;
      &lt;script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"&gt;&lt;/script&gt;
  
  &lt;/body&gt;</code></pre>
  </div>
  </div>

  <p>As you can see, i added an inline style to anchor so that the font is blue.</p>
  
  <p>However, when i write the CSS style into the  at the head section, the desired CSS effect does not get achieved. It was totally perfect to get the desired CSS effect by writing an inline style. Can anyone explain?</p>
