【问题描述】：

我对 css/html 比较陌生。我一直在浏览这个问题一段时间，但没有找到解决方案。

问题是，如果我使用下面的代码（使用 Bulma），可点击区域什么时候悬停在img3.jpg 上是整个街区从第一个 <div class="columns is-multiline"> 开始。我怀疑这个问题可能是一些布尔玛之间的冲突is-column / is-multiline，以及覆盖 CSS 定义我提供？

<style type="text/css">
  ul {
    list-style: none;
    padding: 10px 10px 10px 30px
  }
  ul li {
    font-size: 120%;
    margin-left: 10px;
    list-style-type: circle;
  }
</style>

<style>
.container {
  position: relative;
  width: 100%;
}

.image {
  display: block;
  width: 100%;
  height: auto;
}

.overlay {
  position: absolute;
  top: 0;
  bottom: 0;
  left: 0;
  right: 0;
  height: 100%;
  width: 100%;
  opacity: 0;
  transition: .5s ease;
  background-color: #008CBA;
}

.container:hover .overlay {
  opacity: 1;
}

.text {
  color: white;
  font-size: 20px;
  position: absolute;
  top: 50%;
  left: 50%;
  -webkit-transform: translate(-50%, -50%);
  -ms-transform: translate(-50%, -50%);
  transform: translate(-50%, -50%);
  text-align: center;
}
</style>

<div class="columns is-multiline">
  <div class="column is-9">
    <div class="content">
      <h3> About us </h3>
      <hr>

    <p align="left" style="font-size:120%;">
