Html 如何将整页彩色背景添加到加载动画的单个元素中？

我有一个html div，用于加载屏幕元素。我需要添加一个完整的页面背景色。换句话说，我需要旋转图像位于纯色整页背景之上

而且，我只能使用一个元素。以下是我到目前为止的情况：

.animsition-loading {
    background-image: url('../images/logo-loading.png');
    width: 100px;
    height: 111px;
    background-repeat: no-repeat;
    background-size: contain;
    position: fixed;
    top: 50%;
    left: 50%;
    margin-top: -16px;
    margin-left: -16px;
    -webkit-animation: spin1 .5s infinite linear;
    -moz-animation: spin1 .5s infinite linear;
    -o-animation: spin1 .5s infinite linear;
    -ms-animation: spin1 .5s infinite linear;
    animation: spin1 .5s infinite linear;
}

@-webkit-keyframes spin1 {
    0% { -webkit-transform: rotate(0deg);}
    100% { -webkit-transform: rotate(360deg);}
}
@-moz-keyframes spin1 {
    0% { -moz-transform: rotate(0deg);}
    100% { -moz-transform: rotate(360deg);}
}
@-o-keyframes spin1 {
    0% { -o-transform: rotate(0deg);}
    100% { -o-transform: rotate(360deg);}
}
@-ms-keyframes spin1 {
    0% { -ms-transform: rotate(0deg);}
    100% { -ms-transform: rotate(360deg);}
}
@-keyframes spin1 {
    0% { transform: rotate(0deg);}
    100% { transform: rotate(360deg);}
}

您可以使用psuedo元素。如果容器覆盖了整个视口，则绝对将psuedo after元素放置在中心，如下所示：

.animation-loading{
    position: fixed;
    width: 100vw;
    height: 100vh;
    background-color: YOUR_COLOUR;
}    

.animation-loading::after{
    content: "";
    display: block;
    background-image: url('../images/logo-loading.png');
    width: 100px;
    height: 111px;
    background-repeat: no-repeat;
    background-size: contain;
    position: absolute;
    top: 50%;
    left: 50%;
    margin-top: -16px;
    margin-left: -16px;
    -webkit-animation: spin1 .5s infinite linear;
    -moz-animation: spin1 .5s infinite linear;
    -o-animation: spin1 .5s infinite linear;
    -ms-animation: spin1 .5s infinite linear;
    animation: spin1 .5s infinite linear;
}

@-webkit-keyframes spin1 {
    0% { -webkit-transform: rotate(0deg);}
    100% { -webkit-transform: rotate(360deg);}
}
@-moz-keyframes spin1 {
    0% { -moz-transform: rotate(0deg);}
    100% { -moz-transform: rotate(360deg);}
}
@-o-keyframes spin1 {
    0% { -o-transform: rotate(0deg);}
    100% { -o-transform: rotate(360deg);}
}
@-ms-keyframes spin1 {
    0% { -ms-transform: rotate(0deg);}
    100% { -ms-transform: rotate(360deg);}
}
@-keyframes spin1 {
    0% { transform: rotate(0deg);}
    100% { transform: rotate(360deg);}
}

您可以使用此HTML加载循环：

<div id='loading-bg' style='display:none; position:fixed; z-index:9999; top:0; right:0; bottom:0; left:0; background-color:rgba(0,0,0,0.4); width:100%; height:100%;'><div id='floatingCirclesG' style='position:fixed; top:50%; left:50%; margin-left:-64px; margin-top:-64px;'><div class='f_circleG' id='frotateG_01'></div><div class='f_circleG' id='frotateG_02'></div><div class='f_circleG' id='frotateG_03'></div><div class='f_circleG' id='frotateG_04'></div><div class='f_circleG' id='frotateG_05'></div><div class='f_circleG' id='frotateG_06'></div><div class='f_circleG' id='frotateG_07'></div><div class='f_circleG' id='frotateG_08'></div></div></div>

…你完了！在这里拉小提琴：

不幸的是，没有。该示例将加载元素包装在一个div周围。包装器div是应用背景色的元素。

#floatingCirclesG{
