ad unit margins and captions

I would like to insert a margin of 50px below and above each ad unit.

edit this line:

margin: 100px 0px 100px 0;

Can you suggest how the code for a div inside the stylesheet would look like and where I would insert it on the main pages?

you can’t insert a div or any html code into a stylesheet.

the adding of a caption will depend on how the ads are inserted right now.

a link to your site might help to illustrate your problem.

where you have this now: (caution – i obscured your personal numbers)

/*
commented google adsense<div
class="adsensead"> <script type="text/javascript">google_ad_client = "pub-12345678899";
/* 728x90, created 4/22/10 */
google_ad_slot = "0987654433";
google_ad_width = 728;
google_ad_height = 90;</script> <script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script> </div> commented google adsense
*/

try:

<div
class="adsensead"><span>some caption title</span><script type="text/javascript">google_ad_client = "pub-12345678899";
/* 728x90, created 4/22/10 */
google_ad_slot = "0987654433";
google_ad_width = 728;
google_ad_height = 90;</script> <script type="text/javascript"
src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script> </div>

and edit header.php to make sure that there is no script before the ‘doctype’ declaration.

untested:

.adsensead span { display:block; width: 100%; }
.adsensead { margin: 50px 0px; }

for more suggestion, the adsense unit needs to be activated and visible in your link – this makes it easier to check and suggest changes to the stylesheet.
