Html 如何在我的网站页脚添加正确对齐的Facebook和Twitter按钮？

我将Volusion用于我的电子商务网站，并希望在我的网站页脚添加Facebook和Twitter按钮/图标（类似于此页面页脚中的“cc wiki”和“Peak Internet”徽标）

下面是我的页脚的当前HTML代码。我应该添加什么代码使版权和“Powered by Volusion”文本左对齐，并在同一行中添加所需的按钮，但右对齐

<div id="footer_bottom">
    <!--<div id="footer_right" class="right">-->

    <!--</div>-->
    <div id="copyright">
        <a href="/terms.asp">Copyright &copy; <script type="text/javascript">document.write((new Date()).getFullYear());</script>  &nbsp;Config_CompanyNameLegal&nbsp; All Rights Reserved.</a>

        <!-- ==========================================================================================
            VOLUSION LINK - BEGIN
        ===============================================================================================
        Customer has agreed per Volusion’s Terms of Service (http://www.volusion.com/agreement_monthtomonth.asp) to maintain a text hyperlink to "http://www.volusion.com" in the footer of the website. The link must be standard html, contain no javascript, and be approved by Volusion. Removing this link breaches the Volusion agreement.-->   

        <br><a style="color: #F0F0F0" href="http://www.volusion.com" title="Shopping Cart Software" target="_blank">Powered by Volusion</a>
    </div>
    <!-- ==========================================================================================
        VOLUSION LINK - END
    =========================================================================================== -->    
    </div>
</div>

您必须在div上使用

float:left

或

float:right

（在某种程度上，这种效果，未经测试只需使用CSS即可）

<div id="footer_bottom" style="display: block; width: 100%">
    <div id="powered" style="float: left">Powered by Volusion</div>

    <!--</div>-->
    <div id="copyright" style="float:right" ><a href="/terms.asp">Copyright &copy; <script type="text/javascript">document.write((new Date()).getFullYear());</script>  &nbsp;Config_CompanyNameLegal&nbsp; All Rights Reserved.</a>
     </div>
</div>

/* CSS */
#powered {
   float: left;
}
