can i use external stylesheet to add "share this" button to my entire site

Hi all, new to this site, hoping someone can help me out cause I cant find answers anywhere.

Basically I want to add a "share this" button to all the pages on my site, is there a quick way of doing this? maybe using an external stylesheet or something?

any advice would be much appreciated,

thanks in advance

Is there any file they all link to? It can be css, js, or any file that can include html. If there isn't one already, you will need to edit them all, anyway. I might be able to write a script to add it to all of them for you, though, if you want it in the same place on every page.

 

That would be absolutely briiliant if you could, I really appreciate it. Im still learning the ropes and this has had me stumped for a while. Yeah I want it in the same position on every page, bottom right or left, after all the content within the body div. this is the html code I have for my "share it" button.

<!-- AddThis Button BEGIN -->
<div class="addthis_toolbox addthis_default_style">
<a href="http://www.addthis.com/bookmark.php?v=250&amp;username=woscraig" class="addthis_button_compact">Share</a>
<span class="addthis_separator">|</span>
<a class="addthis_button_facebook"></a>
<a class="addthis_button_myspace"></a>
<a class="addthis_button_google"></a>
<a class="addthis_button_twitter"></a>
</div>
<script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#username=woscraig"></script>
<!-- AddThis Button END -->

 

Could you give an example of the html for the body div, and around the body div? Is it the last div in the body? If not, what tag follows it? I would like id's or other identifying attributes. I shouldn't need the content in the div, but if it should always follow the same thing on each page it would simplify the script. Also, if you aren't on Windows, I'll need to brush up on whatever scripting your system uses.
