Previously I already wrote how to add Facebook like button to your site, using a simple module. Today I'll how how to add floating social share buttons using custom code:

Here is an example page:

This will work for Facebook, Twitter and Google + buttons:

Add this code to your theme files:

<div id="pageshare">
<div class="sbutton" id="fb">
<a name="fb_share"type="box_count" href="http://www.facebook.com/sharer.php">Share</a><script src="http://static.ak.fbcdn.net/connect.php/js/FB.Share" type="text/javascript"></script>
</div>
<div class="sbutton" id="rt">
<a href="https://twitter.com/share" class="twitter-share-button" data-count="vertical">Tweet</a><script type="text/javascript" src="//platform.twitter.com/widgets.js"></script>
</div>
<div class="sbutton" id="gplusone">
<script type="text/javascript" src="http://apis.google.com/js/plusone.js"></script>
<g:plusone size="tall"></g:plusone>
</a></div>
</div>

And add following lines of CSS to your stylesheet:

#pageshare {position:fixed; top:35%; margin-left:-100px; float:left; border-radius:5px;-moz-border-radius:5px;-webkit-border-radius:5px;background-color:#ffffff;padding:0 0 2px 0;z-index:10;}
#pageshare .sbutton {float:left;clear:both;margin:6px;}
.fb_share_count_top {width:48px !important;}
.fb_share_count_top, .fb_share_count_inner {-moz-border-radius:3px;-webkit-border-radius:3px;}
.FBConnectButton_Small, .FBConnectButton_RTL_Small {width:49px !important; -moz-border-radius:3px;/*bs-fsmsb*/-webkit-border-radius:3px;}
.FBConnectButton_Small .FBConnectButton_Text {padding:2px 2px 3px !important;-moz-border-radius:3px;-webkit-border-radius:3px;font-size:8px;}

That's all. You can add more buttons to code if you like to.
