title: Can the order in which adding link and meta tags on head of a webpage have any adverse effect?
body: <p>I have added this code to my webpage with .php extension</p>
  
  <pre class="lang-php prettyprint-override"><code>&lt;?php include_once("cssheadertop.php")?&gt;
  &lt;link rel="stylesheet" href="button.css"&gt;
  &lt;?php include_once("cssheaderbottom.php")?&gt;
  </code></pre>
  
  <p>Now, cssheadertop.php contains the following code</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;head&gt;
  &lt;meta charset="utf-8"&gt;
  &lt;title&gt;8mags - CSS Lessons&lt;/title&gt;
  &lt;meta name="viewport" content="width=device-width, initial-scale=1"&gt;
  &lt;link rel="stylesheet" href="../../bootstrap.min.css" media="screen"&gt;
  &lt;link rel="stylesheet" href="../../style.css"&gt;
  &lt;link href='http://fonts.googleapis.com/css?family=Roboto+Condensed' rel='stylesheet' type='text/css'&gt;
  &lt;link href='http://fonts.googleapis.com/css?family=Coda' rel='stylesheet' type='text/css'&gt;
  &lt;script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>The cssheaderbottom.php file has following code</p>
  
  <pre class="lang-html prettyprint-override"><code>  &lt;style&gt;
    page specific style here.
    &lt;/style&gt;
    &lt;/head&gt;
  </code></pre>
  
  <p>I want to add meta description and meta keywords tag between </p>
  
  <pre class="lang-php prettyprint-override"><code> &lt;?php include_once("cssheadertop.php")?&gt; 
  </code></pre>
  
  <p>and </p>
  
  <pre class="lang-php prettyprint-override"><code> &lt;?php include_once("cssheaderbottom.php")?&gt;
  </code></pre>
  
  <p>just like the link tag I have added.</p>
  
  <p>Can it pose any problem in rendering or SEO?</p>
