【问题描述】：
使用 CSS 网格，我在网格中有按钮和一个 div。该 div 也是一个包含更多按钮和 div 的网格。主网格中的按钮工作正常，但子网格中的按钮不会响应单击或悬停事件。我有一个 CSS 伪选择器，可以在悬停时使开始按钮上的颜色反转，但它不起作用，我有一个 jQuery 选择器，可以在您单击它时使严格模式按钮反转颜色，然后反转回来第二次点击，但它也不起作用。
$(document).ready(function() {
$(".header").html("<h1 class='text-center'>Simon</h1>");
$(".count").html("—");
$(".start").html("<i class='fas fa-play'></i>");
$(".strict").html("Strict<br>Mode");
var strict = false;
$(".strict").click(function() {
if (strict) {
$(this).css("background", "#efefef");
$(this).css("color", "#262626");
strict = true;
} else {
$(this).css("background", "#262626");
$(this).css("color", "#efefef");
strict = true;
}
