js代碼部分遇新是直朋能到：
var btn = document.getElementById('open_btn');
var div = document.getElementById('background');
var close = document.getElementById('close-button');
btn.onclick = function show() {
div.style.display = "block";
}
close.onclick = function close() {
div.style.display = "none";
}
window.onclick = function close(e) {
if (e.target == div) {
div.style.display = "none";
}
}
