我一直在嘗試用jQuery淡出CSS3預加載器。我一直試圖停止動畫（這是一個旋轉的盒子），然後淡入盒子裏面的一封信，然後讓它們都淡出，信件比盒子晚一點。我遇到了這樣的問題，即信件在比我想要的時間晚的地方消失，並且如果淡出的速度非常快，則會出現這種情況。下面是代碼：jQuery的延遲淡入時間比預期的要長
\t //<![CDATA[
$(window).load(function() { // makes sure the whole site is loaded
$('.loader-inner').css({'-webkit-animation': 'none'});
$('.loader').delay(100).css({'-webkit-animation': 'none'}); // will first fade out the loading animation
$('.letter').delay(100).fadeIn('slow');
$('.preloader').delay(2050).fadeOut('slow');// will fade out the white DIV that covers the website.
$('.letter').delay(2060).fadeOut(900);
$('body').delay(2060).css({'overflow':'visible'});
\t \t });
