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

Apart from a few exceptions, the order of childs in the head element doesn’t matter.
That said, consumers like search engines may of course do what they want (e.g., ignoring every third element, just for the fun of it), but discussing the possible behaviour of undesignated consumers is off-topic here.
The exceptions:
meta–charsetshould ideally be the first child (i.e., the element must be within the first 1024 bytes of the document, and at best before any non-ASCII characters)baseshould ideally be the second child (i.e., it must come before any other element inheadthat has a URI as attribute value)those
