#preloader { 
height: 60px; 
width: 60px; 
position: absolute; 
top: 50%; 
left: 50%; 
margin-top: -20px; 
margin-left: -20px; 
} 
#preloader:before { 
content: ""; 
display: block; 
position: absolute;

#preloader > .icon {

/*top: 50%; 
left: 50%;*/ 
height: 60px; 
width: 60px; 
/*margin-top: -12.5px; 
margin-left: -5.3px;*/ 
-webkit-animation: 1s ease-in-out infinite alternate; 
animation: 1s ease-in-out infinite alternate; 
} 
@media only screen and (min-width: 768px) { 
#preloader { 
height: 80px; 
width: 80px; 
margin-left: -30px; 
} 
#preloader:before {

} 
}

height: 100px; 
width: 100px; 
margin-top: -40px; 
margin-left: -40px; 
} 
#preloader > .icon {

@-webkit-keyframes rotation {

-webkit-transform: rotate(359deg); 
transform: rotate(359deg);

} 
@keyframes rotation {

transform: rotate(0deg); 
} 
to { 
-webkit-transform: rotate(359deg); 
transform: rotate(359deg); 
} 
} 
@-webkit-keyframes wink {

opacity: 1; 
} 
} 
@keyframes wink {

opacity: 0;

} 
} 
</style> 
<div id="preloader" aria-busy="true" aria-label="Loading, please wait." role="progressbar"><img class="icon" src="URL OF GIF"> 
</div> 
<main id="site" role="main"></main> 
<script type="text/javascript"> 
(function(){ 
var preload = document.getElementById("preloader"); 
var loading = 0; 
var id = setInterval(frame, 64); 
function frame(){ 
if(loading == 100){ 
clearInterval(id); 
//window.open('welcome.html', '_self'); 
} else { 
loading = loading + 1; 
if(loading == 90){ 
preload.style.opacity = "0"; 
} 
} 
} 
})(); 
/*(function preloader() { 
var preloader = document.getElementById("#preloader"); 
preloader.style.opacity = "0"; 
preloader.setAttribute("aria-busy", "false"); 
document.getElementById("#site").style.opacity = "1"; 
}) 
window.onload = preloader;*/ 
</script>

现在我有一个白色背景，我希望背景是纯黑色。我尝试过一些东西但似乎没什么用。

我正在从网址加载GIF。

我知道Black的颜色代码是＃000000而我尝试输入它而不是 opacity = 0; 但似乎没有任何效果。

有什么建议吗？
