Webkit过滤器删除阴影

Question

我无法覆盖（或简单地删除）放置在下图中可以看到的文本上的-webkit-filter drop-shadow属性。我需要讲话泡泡上的阴影，但不要在泡泡下方的文字上。我已经尝试将阴影设置为白色，但似乎没有效果。出于定位原因，我需要将文本保留为泡泡的子元素。谁能告诉我如何达到预期的效果呢？

HTML

<div class="bubble bubble-left">This is line 1 in speech bubble left.<br/> 
      This is line 2 in the bubble,<br/> and this is line 3.
      <div class="title">Title for bubble</div>
</div>

CSS

.bubble {

尝试将过滤器框影子CSS属性更改为以下格式：

 -webkit-drop-shadow: (4px 4px 5px rgba(0, 0, 0, 0.5));
 -moz-drop-shadow: (4px 4px 5px rgba(0, 0, 0, 0.5));
 -ms-drop-shadow: (4px 4px 5px rgba(0, 0, 0, 0.5));
 -o-drop-shadow: (4px 4px 5px rgba(0, 0, 0, 0.5));

您可能需要根据自己的喜好调整框阴影值：

另一种方法是从泡泡容器中取出泡泡链接的标题，并将它们放在一个新的相对div中。您必须对CSS进行一些更改。

<div class="wrap">
        <div class="bubble bubble-left">This is line 1 in speech bubble left.
            <br/>This is line 2 in the bubble,
            <br/>and this is line 3.</div>
        <div class="title">Title for bubble</div>
    </div>
