我有这个代码来显示登录 facebook 按钮

<span style="float:right; height:40px; line-height:45px;vertical-align:top; 
font-size:14px; padding-right:10px; "><?php if($this->tank_auth->is_logged_in())
{    echo "Welcome " .anchor('profile',$this->tank_auth->get_username())." | ".anchor
    ('profile/find_friends','Find Friends')." | ".anchor('auth/logout','Logout');} 
   else {?><?php echo  anchor('auth/login','Login'); ?> | 
  <fb:login-button v="2" perms="" length="long" 
  onlogin='window.location="https://graph.facebook.com/oauth/authorize?client_id=<?php echo  
$this->config->item('facebook_app_id'); ?>&redirect_uri=<?php echo site_ur
('auth_other/fb_signin'); ?>&amp;r="+window.location.href;'></fb:login-button><?php } ?></span>
            <div style="clear:both"></div>

当我浏览页面时,此代码将转换为此:

<fb:login-button v="2" perms="" length="long" 
   onlogin="window.location=&quot;https://graph.facebook.com/oauth/authorize? 
   client_id=372198139465874&amp; 
  redirect_uri=http://allviralvideo.org/auth_other/fb_signin&amp;r=&quot;+window.location.href;" 
  login_text="" class=" fb_iframe_widget" fb-xfbml-state="rendered" fb-iframe-plugin-  
  query="app_id=372198139465874&amp;locale=en_US&amp;sdk=joey">
  **<span style="vertical-align: bottom; width: 69px; height: 22px; ">**<iframe 
  name="f1d6c3fee8" width="1000px" height="1000px" frameborder="0" allowtransparency="true" 
  scrolling="no" title="fb:login_button Facebook Social Plugin" style="border-top-style: none; 
  border-right-style: none; border-bottom-style: none; border-left-style: none; border-width: 
  initial; border-color: initial; width: 69px; height: 22px; visibility: visible; " 
  src="http://www.facebook.com/plugins/login_button.php?app_id=372198139465874&amp;channel=http%3A%2F%2Fstatic.ak.facebook.com%2Fconnect%2Fxd_arbiter.php%3Fversion%3D28%23cb%3Df11db3306c%26domain%3Dallviralvideo.org%26origin%3Dhttp%253A%252F%252Fallviralvideo.org%252Ff72d2ade4%26relation%3Dparent.parent&amp;locale=en_US&amp;sdk=joey" class=""></iframe></span></fb:login-button>

我想删除垂直对齐:底部;从粗体部分。我添加了垂直对齐:顶部;到父标签,但它会抑制它们。有什么办法可以去掉这个吗?

您可以使用 Facebook 按钮的直接父级来定位 CSS 中的跨度。就像是:

.parent span {
    vertical-align: top !important;
}

由于它正在生成内联样式,因此您需要使用 !important 否则它将被覆盖。

您也可以直接在 CSS 中定位 fb 元素,但我从未使用过它,所以我不能确定。
