I did everything what u said and come to a conclusion that this is happening because of adsence code. Whenever i am putting any adsence code anywhere at the page a big blank space created. Do you know anything about this.

<script async src=”https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js”></script&gt;
<!– Fixed Header Ad –>
<ins class=”adsbygoogle”
style=”display:inline-block;width:728px;height:90px”
data-ad-client=”ca-pub-4567097199590531″
data-ad-slot=”6934473625″></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>

this is the code i am using

and thanks for your response.
