I would like to add space between banners on my home page,
To add white space between each banner to create clarity,
I do not know if this is CSS or HTML or PHP coding
the website is: http://trade-th.com/
the banners are on the Left Side as you scroll down the page,
you will see a Banner saying - Your 500 x 90 Banner Ad here for $5 a month
all help appreciated 
I assume you want to add vertical space between the ad banners. The following should do the trick:
.vert_banners + .vert_banners {
margin-top:25px;
}
Change the margin value to suit yourself, of course 
Hope this helps.
Hello ronpat,
thank you, yes adding vertical space between the banners is what I would like to achieve,
now where do I place your code ?
do I place it with each Banner code ? for example below ?
<a href=“http://www.tkqlhce.com/click-7033326-10356149” target=“_blank” onmouseover=“window.status=‘http://www.serverpronto.com/’;return true;” onmouseout=“window.status=’ ';return true;”>
<img src=“http://www.ftjcfx.com/image-7033326-10356149” width=“500” height=“90” alt=“ServerPronto Dedicated Servers, Click for details.” border=“0”/></a>
Add it to the style.css stylesheet below line 633.
