Align Button to Right
How do I get this button aligned to the right, and how do I change its dimensions?
<!-- AddThis Button BEGIN -->
<div class="addthis_toolbox addthis_default_style">
<a class="addthis_button_preferred_1"></a>
<a class="addthis_button_preferred_2"></a>
<a class="addthis_button_preferred_3"></a>
<a class="addthis_button_preferred_4"></a>
<a class="addthis_button_compact"></a>
</div>
<script type="text/javascript" src="http://s7.addthis.com/js/250/addthis_widget.js#pubid=xa-4f8d0830076d7552"></script>
<!-- AddThis Button END -->
Thanks in advance!
Do you know CSS?
