Question

我有一个“灯箱”类型的og图像查看器，用于浏览某些图像。

图像的纵横比不同，我需要将箭头放在边缘。当我调整网页大小时，图像会遵循网页的大小，这很好

但是，箭头只是从图像上浮下来：(有什么想法吗？

body {
    background-image: url("../img/bg-masthead.jpg");
    height: 100%;
    background-position: center;
    background-repeat: no-repeat;
    background-size: cover;
    background-attachment: fixed;
    margin: 0;
}

.modal {
    position: fixed;
    width: 100%;
    height: 1000%;
    background-color: rgba(0, 0, 0, 0.4);
    /* display: none; */
}

.modal-content {
    display: inline-block;
    width: 95%;
    height: 95%;
    position: fixed;
    top: 40px;
    left: 50%;
    transform: translate(-50%, 0);
}

img {
    object-fit: contain;
    max-width: 100%;
    max-height: 100%;
    width: auto;
    height: auto;
    display: block;
    margin-left: auto;
    margin-right: auto;
}

.prev {
    top: 50%;
    left: 8px;
}

.close {
    top: 4px;
    right: 8px;
}

.next {
    top: 50%;
    right: 8px;
}

.arrow {
    position: absolute;
    color: white;
    font-weight: bold;
    font-size: 50px;
    cursor: pointer;
}
