悬停时不会出现伪元素

时间：2016-09-01 03:05:55

标签： jquery html css3 hover pseudo-element

我正在尝试设置幻灯片上的按钮样式，以便在使用伪元素：之前（宽度100％）悬停时填充。但是，悬停时不会显示伪元素，即使在从Chrome开发者工具切换悬停状态时也是如此。 

<div class="featured-slider">
            <div class="featured-profile banner__wrapper js-pause">

                <span class="banner__nav left js-banner__left"></span>
                <span class="banner__nav right js-banner__right"></span>

                <div class="banner__container">

您需要从position: absolute;中移除.banner__slide a，然后将所有内容删除：

.banner__slide a:hover span.button-hollow:before {
  width: 100%;
}
