HTML hover image: expand clickable area beyond image

I am relatively new to css/html. I've been browsing around this issue for a while but haven't found a solution.

The problem is that if I use the code below (using Bulma), when hovering on img3.jpg, the clickable area is removed from The first

starts with the entire block . I suspect the problem may be a conflict between Bulma's is-column/is-multiline, and the overriding CSS definitions I provide ?

<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>
