Div悬停仅在底部工作

Question

我正在尝试将div设为一个链接，在悬停时应该放大并显示另一个叠加div。这就是我所拥有的。它可以工作，但不是div的所有部分都与悬停一起工作。它只能在div的底部工作，但不能在其他任何地方工作。

请问我做错了什么？

我已将我的代码放在下面。有趣的是它如何适用于background-home-row-2并且不适用于.background-home-row-1。我在省什么？

$("a.image").hover(function() {
  $(".background-home-row-1 .visible-on-hover").css("display", "block");
}, function() {
  var mq = window.matchMedia("(min-width : 320px) and (max-width : 480px)");
  if (!mq.matches) {
    $(".background-home-row-1 .visible-on-hover").css("display", "none");
  }
});


$(".background-home-row-2").hover(function() {
  $(".background-home-row-2 .visible-on-hover").css("display", "block");
}, function() {
  var mq = window.matchMedia("(min-width : 320px) and (max-width : 480px)");
  if (!mq.matches) {
    $(".background-home-row-2 .visible-on-hover").css("display", "none");
  }
});

.image-box {
  padding: 0px;
  margin: 0px;
  display: block;
}
.background-home-row-1 .visible-on-hover,
.background-home-row-2 .visible-on-hover {
