试试这个:-

我稍微改了一下。变化:-

1).给定 Id 到 Span 标签

2).更改了 JS 中有关 Span 的代码

3).正确关闭html中的div和img标签。

4).在 css 文件中添加类 (.modal-backdrop)

    // Get the modal
    var modal = document.getElementById('myModal');

    // Get the button that opens the modal
    var btn = document.getElementById("myBtn");

    // Get the <span> element that closes the modal
    var span = document.getElementById("CloseModal");

    // When the user clicks the button, open the modal
    btn.onclick = function () {
        modal.style.display = "block";
    }

    // When the user clicks on <span> (x), close the modal
    span.onclick = function () {
        modal.style.display = "none";
    }

    // When the user clicks anywhere outside of the modal, close it
    window.onclick = function (event) {
        if (event.target == modal) {
            modal.style.display = "none";
        }
    }

/* The Modal (background) */
