我猜猜想。黑色图像是占位符(因为你拥有的其他东西看起来像占位符)。我猜你正在寻找CSS来制作图像周围的帧,也许是如何"浮动"他们在彼此之上?
.float-stuff-relative-to-this-div {
position: relative;
}
.image-frame{
border: 5px solid white;
box-shadow: 0 1px 3px black;
}
.floaty-float{
position: absolute;
top: 20px;
left: 20px;
/* Puts it behind stuff with higher z-index (default is 0) */
z-index: -1;
}

<div class="float-stuff-relative-to-this-div">
<img class="image-frame" src="http://via.placeholder.com/200x200/000000/000000">
<img class="image-frame floaty-float" src="http://via.placeholder.com/200x200/000000/000000">
</div>
