我使用了以下代码的Sanitize Ruby gem：
result = Sanitize.clean(html)
它从页面中提取内容，但我仍然在清理结果中使用此CSS。我如何摆脱它，所以我只有页面文本？
#fsb-social-bar { width: 100%; border-bottom: 1px solid #dbdbdb; border-top: 1px solid #dbdbdb; padding: 10px 0; margin: 0px 0 20px 0; float: left; background: #fff; position: relative; clear: both; } #fsb-social-bar a { border: 0px !important } #fsb-social-bar.fsb-fixed { position: fixed; top: -2px; z-index: 99999; } #fsb-social-bar .fsb-title { display: block; float: left; margin: 3px 20px 0 0; font-size: 16px; font-family: Arial, Helvetica, sans-serif; text-decoration: none; color: #333; } #fsb-social-bar .fsb-share-facebook { width: 120px; float: left; padding: 3px 0 2px; height: 25px; } #fsb-social-bar .fsb-share-facebook.fsb-hide-count { width: 44px; overflow: hidden; margin-right: 30px; } #fsb-social-bar .fsb-share-twitter { float: left; width: 135px; padding: 3px 0 2px; height: 25px; } #fsb-social-bar .fsb-share-twitter.fsb-hide-count { width: 61px; overflow: hidden; margin-right: 30px; } #fsb-social-bar .fsb-share-google { float: left; width: 105px; padding: 3px 0 2px; height: 25px; } #fsb-social-bar .fsb-share-google.fsb-hide-count { width: 33px; overflow: hidden; margin-right: 30px; } #fsb-social-bar .fsb-share-linkedin { float: left; width: 135px; padding: 3px 0 2px; height: 25px; } #fsb-social-bar .fsb-share-linkedin.fsb-hide-count { width: 61px; overflow: hidden; margin-right: 30px; } #fsb-social-bar .fsb-share-pinterest { float: left; width: 115px; padding: 3px 0 2px; height: 25px;} #fsb-social-bar .fsb-share-pinterest.fsb-hide-count { width: 43px; overflow: hidden; margin-right: 30px; } #fsb-social-bar .socialite { display: block; position: relative; background: url(http://www.example.net/wp-content/plugins/floating-social-bar/images/fsb-sprite.png) no-repeat scroll 0 0; } #fsb-social-bar .socialite-loaded { background: none !important; } #fsb-social-bar .fsb-service-title { display: none; } #fsb-social-bar a { color: #333; text-decoration: none; font-size: 12px; font-family: Arial, Helvetica, sans-serif; } #fsb-social-bar .fsb-twitter { width: 105px; height: 25px; background-position: -13px -10px; line-height: 25px; vertical-align: middle; } #fsb-social-bar .fsb-twitter .fsb-count { width: 30px; text-align: center; display: inline-block; margin: 0px 0 0 69px; color: #333; } #fsb-social-bar .fsb-google { width: 75px; height: 25px; background-position: -136px -10px; line-height: 25px; vertical-align: middle; } #fsb-social-bar .fsb-google .fsb-count { width: 30px; text-align: center; display: inline-block; margin: 0px 0 0 41px; color: #333; } #fsb-social-bar .fsb-google .socialite-button { margin: 0 !important; } #fsb-social-bar .fsb-share-google .socialite-loaded .socialite-button{padding: 2px 0 0} #fsb-social-bar .fsb-facebook { width: 89px; height: 25px; background-position: -231px -10px; line-height: 25px; vertical-align: middle; } #fsb-social-bar .fsb-facebook .fsb-count { width: 30px; text-align: center; display: inline-block; margin: 0px 0 0 52px; color: #333; } #fsb-social-bar .fsb-facebook .socialite-button { margin: 0 !important;} #fsb-social-bar .fsb-share-facebook .socialite-loaded .socialite-button {padding: 2px 0 0} #fsb-social-bar .fsb-linkedin { width: 105px; height: 25px; background-position: -347px -10px; line-height: 25px; vertical-align: middle; } #fsb-social-bar .fsb-linkedin .fsb-count { width: 30px; text-align: center; display: inline-block; margin: 0px 0 0 70px; color: #333; } #fsb-social-bar .fsb-linkedin .socialite-button { margin: 0 !important; } #fsb-social-bar .fsb-pinterest { width: 88px; height: 25px; background-position: -484px -10px; line-height: 25px; vertical-align: middle; } #fsb-social-bar .fsb-pinterest .fsb-count { width: 30px; text-align: center; display: inline-block; margin: 0px 0 0 50px; color: #333; } #fsb-social-bar .fsb-pinterest .socialite-button { margin: 0 !important; } #fsb-social-bar .fsb-clear { clear: both; } #fsb-social-bar .fsb-clear:after { clear:both; content:; display:block; height:0; line-height:0; overflow:auto; visibility:hidden; zoom:1; } @media (max-width: 768px) { #fsb-social-bar.fsb-fixed { position: relative !important; top: auto !important; } } Facebook2 Twitter1 Google+0 LinkedIn0 Pinterest0 Lorem ipsum dolor sit amet, consectetur adipiscing elit.

解决方案不仅需要处理此文本，还需要处理可能碰巧拥有CSS的任何字符串。谢谢你的帮助。

如果你的CSS代码在样式标记内，你可以使用这个：
Sanitize.clean(content, :remove_contents => ['script', 'style'])
其他解决方案是css_transformer.rb。
