fb like positioning

I have problem because fb like is not aligned with other buttons.
When I try to align with css it is not working because there is some inline style loading from somewhere I can not find where.

<span style="text-decoration:none;color:#000000;display:inline-block;cursor:pointer;position: absolute;margin: 1px 5px 0;padding: 0;font-size:11px;line-height:16px;vertical-align: baseline;overflow:visible;">

If you can show me where to apply this changes I would be very thankful and use this plugin.
