How do I center align adsense ads?
Like the picture attached

Example forums.digitalpoint.com

Is it a special product or code or what ? ​

 

Adsense Background is same as Digital Point Template of Post.

 

What you mean by center align?? That ad is right aligned.

May be I didn't get your question.

 

what he ask is he want it in the medal of the post not before or after within the post

 

<center> PUT CODE HERE</center>

or 

[center]PUT CODE HERE[/center]

or 

<span style="padding-left:300px"></span>PUT CODE HERE

Code (markup):

 

You can also ad this line of code before your adsense code.

<div style='float:left;'>
Your adsense code
</div>
