图像悬停样式无法实现

标签： html css twitter-bootstrap

我是引导程序的新手，并尝试在悬停时实施背景颜色更改。 好吧，这正在发生，但不是完美的。需要以这种方式实现。

轮播容器后有这种全高悬停效果。

我尝试过填充和最小高度，但仍然无法实现。

Styles.css 

.application-container .image-container:hover{
    background-color: #EFF3F6;
  }

  .application-container .image-container {
    position: relative;
  }

  .application-container .image-container:hover:after {
   content: "";
   display: block;
  border-left: 10px solid transparent;
    border-right: 10px solid transparent;
    border-bottom: 10px solid #EFF3F6;
   position: absolute;
   left: 45%;
   bottom: 66px;
  }

实现上面的代码后，我得到的就是这样。 悬停效果应在轮播和应用容器之间 我尝试使用line-height属性，但是不起作用。 有人可以帮忙/指导我吗。

在display: inline-block; padding: 20px;中添加.application-container .image-container将完成您的工作，

希望这会有所帮助

在.py-*上添加类py-1（即.image-container）以增加间距。

据我了解，更改了样式并获得以下输出：

对于此更改，请更新以下样式：

.application-container .image-container {
     position: relative;
    display: inline-block;
    padding: 20px;
    cursor: pointer;
  } 

  .application-container .image-container:hover:after {
   content: "";
   display: block;
  border-left: 10px solid transparent;
    border-right: 10px solid transparent;
    border-bottom: 10px solid #EFF3F6;
   position: absolute;
   left: 45%;
       top: -10px;
  }

我认为它应该对您有用：https://jsfiddle.net/abhineetV/gf4qhswc/26/ 我已经改变了一些结构。

<div class="container application-container">
  <ul class="banner-nav list-unstyled d-flex justify-content-center">
    <li>
      <a href="javascript:void(0);" class="d-flex flex-column"><span class="oi oi-account-login"></span><div>
      account login
      </div></a>
    </li>
    <li>
      <a href="javascript:void(0);" class="d-flex flex-column"><span class="oi oi-pencil"></span><div>
      pencil
      </div></a>
    </li>
    <li>
      <a href="javascript:void(0);" class="d-flex flex-column"><span class="oi oi-shield"></span><div>
      shield
      </div></a>
    </li>
    <li>
      <a href="javascript:void(0);" class="d-flex flex-column"><span class="oi oi-arrow-right"></span> <div>
     View All
     </div></a>
    </li>
  </ul>

</div>

CSS：

.banner-nav>li {
  width: 120px;
}

.banner-nav>li>a {
  height: 100%;
  padding: 15px;
  text-align: center;
  transition: all 0.2s ease;
}

.banner-nav>li>a:hover {
  background-color: #EFF3F6;
}
