how to edit this sidebox content width?

I have this in my sidebox, but its too long i would like to be able to set the height to 160 the width is good how it is... the code is here:

    <SCRIPT src="http://fpm.petfinder.com/fp/petfeed.cgi?lang=json&callback=fpm&state=&shelter=&animal=&age=&ref=iSjUomffeHGERWj"></SCRIPT>   

thanks again!

The information you have given has no way to be connected with a width or height.

The surrounding code with class and/or id tags, and a link to the site, would make it possible to give advice.

is there a way to set the side box to a certain height and not go passed that height, i understand its from their website, but thats the code they gave to me , what i told them i wanted was that code on my site but for in the sidebox just the picture...

You can set the sidebox to a fixed height, though if the image is bigger it will overflow the box.
What do those two script calls generate on your page? An image, multiple items, links, or? How big are they when displaying?

With a link to your site and a description of which sidebox you want these scripts in, I can tell you what to do to fix the size.

Add to your stylesheet```
#bannerbox2Content {height: 160px;}

This will make that box always 160px high. Put your script code in as the banner content and see how it looks.
