使图像边框看起来像包含其他图像的文件夹

Question

你好，我正在尝试制作一个家庭假期图片网站，它有一个包含文件夹的页面，其中包含每天的一张图片，我可以单击每张图片并转到包含所有图片的不同页面那天的照片。

一切看起来都不错，但我想为文件夹页面上的每个图像添加一个边框，我希望边框看起来像一个文件夹，右上角应该比左边高一点等。

我尝试使用一些工具提示 css 样式，它们看起来像一个箭头，但没有用。

希望这个问题足够清楚，这是我能描述的最好的问题。

<div class="container">
    <div class="row">
        <div class="col-lg-3">
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
        </div>
        <div class="col-lg-3">
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
        </div>
        <div class="col-lg-3">
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
        </div>
        <div class="col-lg-3">
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
            <a href="images.html"><img src="image1200.jpg" class="img-fluid img" alt=""></a>
        </div>
    </div>
</div>

和css

.img {
    border: black 5px solid;
    position: relative;
    margin: 5px;
}

.img:hover {
    cursor: pointer;
    opacity: .8;
    box-shadow: 0 0 5px 3px rgba(0, 140, 186, 0.5);
}

.img::before {
    content: " ";
    position: absolute;
    bottom: 100%;
    left: 0;
    margin-right: -5px;
    border-width: 10px;
