标签： css breadcrumbs

无法使用这个简单的代码来使用css。这段代码在我的JSP页面上工作正常，但是我无法使用hovers打开:before和:after的颜色。

Demo

HTML 

<div class="wizard">
   <a class="inicio"><span></span>Anterior</a>
   <a class="badge">
   <span>
   <h:outputText value="#{EController.form.mes} - #{EController.form.ano}" styleClass="tituloMes" style="border-bottom-style: none; border-bottom-width: 0px; height: 14px; font-size: 12pt;vertical-align:initial;">   </h:outputText>
   </span>
   </a>
   <a class="fim"><span></span>Próximo</a>
</div>

在:hover元素上产生pseudo效果时，它应该像:hover:before一样。

在这个例子中，我做了:hover效果。看看DEMO。

.wizard .inicio:hover{
    background: rgb(86, 180, 243);
    color: #FFF;
}
.wizard .inicio:hover:before{
    border-top: 20px solid #FFF;
    border-bottom: 20px inset #FFFFFF;
    border-right: 20px solid rgb(86, 180, 243);
    color: #FFF;
}
.wizard .inicio:hover:after{
    border-top: 20px solid rgb(86, 180, 243);
    border-bottom: 20px inset rgb(86, 180, 243);
    border-right: 20px solid transparent;
    color: #FFF;
}

如前所述，您需要使用:hover:before更改伪元素悬停状态。由于您的示例缺少悬停状态，我已经更进一步清理所有内容以获得完整的解决方案。

所有伪元素都位于其父元素之外，因此它们可以具有可用于任何背景图像或颜色的透明边框。

Here is a complete example!
