下面是我的代码，我使用下面的代码，并在github上部署页面预加载器现在工作。部署后在控制台status.gif中显示一条错误消息，但在本地主机中未显示

为什么？CSS代码：-

body{
    overflow:hidden;
}
#preloader {
    position: fixed;
    top:0;
    left:0;
    right:0;
    bottom:0;
    background-color:var(--clr-light); /* change if the mask should have another color then white */
    z-index: 999999; /* makes sure it stays on top */
}

#status {

    width:300px;
    height:200px;
    position:absolute;
    left:50%; /* centers the loading animation horizontally one the screen */
    top:50%; /* centers the loading animation vertically one the screen */
    background-image:url(/img/status6.gif?); /* path to your loading animation */
    background-repeat:no-repeat;
    background-position:center;
    margin:-100px 0 0 -100px; /* is width and height divided by two */
}

HTML代码：-

<div id="preloader">
    <div id="status">&nbsp;</div>
</div>

JavaScript代码：

<script type="text/javascript">
    setTimeout(function(){        
        $('#preloader').fadeOut();
        $('.preloader_img').delay(150).fadeOut('slow'); 
    }, 5500);
</script>
