tl;DR - 使用这个(https://www.w3schools.com/howto/howto_js_tab_img_gallery.asp(简单的CSS/HTML/JavaScript代码组合，但我坚持使"扩展图像"成为与缩略图本身完全不同的图像。
这可能吗？我将如何编辑以下代码以进行该调整？
上下文：用手工编码的HTML重新创建我的艺术网站，我的缩略图在photoshop中被裁剪，因为我个人不喜欢整个图像作为缩略图的美学原因。下面的代码。
<!-- CSS -->
/* The grid: Four equal columns that floats next to each other */
.column {
float: left;
width: 25%;
padding: 10px;
}
/* Style the images inside the grid */
.column img {
opacity: 0.8;
cursor: pointer;
}
.column img:hover {
opacity: 1;
}
/* Clear floats after the columns */
.row:after {
content: "";
display: table;
clear: both;
}
/* The expanding image container (positioning is needed to position the close button and the text) */
.container {
position: relative;
display: none;
}
/* Expanding image text */
#imgtext {
position: absolute;
bottom: 15px;
left: 15px;
color: white;
font-size: 20px;
}
/* Closable button inside the image */
.closebtn {
position: absolute;
top: 10px;
right: 15px;
color: white;
font-size: 35px;
cursor: pointer;
}
<!-- HTML -->

<!-- Javascript -->
function myFunction(imgs) {
// Get the expanded image
var expandImg = document.getElementById("expandedImg");
// Get the image text
var imgText = document.getElementById("imgtext");
// Use the same src in the expanded image as the image being clicked on from the grid
expandImg.src = imgs.src;
// Use the value of the alt attribute of the clickable image as text inside the expanded image
imgText.innerHTML = imgs.alt;
// Show the container element (hidden with CSS)
expandImg.parentElement.style.display = "block";
}
代码中缺少很多标签，就像所有<head><style>Your Css Code</style></head>
<script>JS code</script>
你写的东西<!-- Image text -->这个<- 所有这些都被称为评论，在任何情况下都不会执行
这是正确的代码：

}

.column {
