如何通过悬停更改整个 div 背景

Question

如何将 div interestBTN 的背景更改为 css？

我的css:

.interestBTN {
  width: 50%;
  height: 35px;
  line-height: 35px;
  border-color: #ACED52;
  border-radius: 10px;
  font-size: 18px;
  color: black;
  text-align: center;
  margin: auto;
  margin-bottom: 30px;
  background-color: #ACED52;
}

div.interestBTN :hover {
  background-color: black;
  color: #ACED52;

}

HTML:

<a href="#"><div class="interestBTN"><strong>Open</strong></div></a>

提前致谢！
