我在我的网站上设计了一个登录信息。
它在笔记本电脑浏览器中正确对齐并显示,但在移动设备中,它显示的非常小。我需要帮助添加一些引导标签,它也可以与移动浏览器兼容。
以下是您可以看到工作的代码段的演示
function PopUp(hideOrshow) {
if (hideOrshow == 'hide') document.getElementById('ac-wrapper').style.display = "none";
else document.getElementById('ac-wrapper').removeAttribute('style');
}
window.onload = function () {
setTimeout(function () {
PopUp('show');
}, 1000);
}

#ac-wrapper {
position: fixed;
top: 90px;
left: 0;
width: 100%;
height: 100%;
/*background: rgba(34,34,34,0.75);*/

/*rgba(255, 255, 255, .6)*/
