js提示层效果，警告提示浮动窗口网页特效，一共就几行代码很简单。结合了少量的svg代码。
const toasts = document.querySelectorAll(".toast");
const toastTriggers = document.querySelectorAll(".toast__trigger");
toastTriggers.forEach((trigger, index) => {
let toastTimeout;
trigger.addEventListener("click", () => {
toasts[index].classList.add("toast--active");
toastTimeout = setTimeout(() => {
toasts[index].classList.remove("toast--active");
}, 3500);
});
toasts[index].addEventListener("click", () => {
toasts[index].classList.remove("toast--active");
clearTimeout(toastTimeout);
});
});
