我正在尝试在鼠标悬停时使标题出现在图像上，但它们都必须具有相同的类。我不知道我所问的是否可能，但我会考虑各种不同的解决方案。这是我目前的代码。

<div class="item">
            <img class="Placeholderimg" src="placeholder.jpg">
            <div class="hovershow1">
                <div class="title">
                    Testing1
                </div>
            </div>
        </a>
    </div>
    <div class="item">
        <img class="Placeholderimg" src="placeholder.jpg">
        <div class="hovershow2">
            <div class="title">
                Testing2
            </div>
        </div>

这是我的CSS代码

.item{
    height: 156px;
    width: 156px;
}

.Placeholderimg{
    height: 156px;
    width: 156px;
    border-radius: 10px;
}

.hovershow1{
    visibility: hidden;
    position: absolute;
    top:0;
    height: 156px;
    width:156px;
    background-color: rgba(40, 40, 40, 0.4);
    border-radius: 10px;
}

.item:hover .hovershow1{
    visibility:visible;
}

.hovershow2{
    visibility: hidden;
    position: absolute;
    top:0;
    height: 156px;
    width:156px;
    background-color: rgba(40, 40, 40, 0.4);
    border-radius: 10px;
}

.item:hover .hovershow2{
    visibility:visible;
}
