i have no how i can able to write in CSS

 

If I understand correctly what you were saying.. you could do this with <center> tag.

<center> Google code </center>

 

If you do want to do it with CSS then put your google ad in a div like so:

<div class="ad">
ad code here
</div>

HTML:

Then in you CSS put:

div.ad {
text-align: center;
}

HTML:

 

Thank you very much for your answer
