CSS容器在父容器之外，也是不可能的

Question

我目前正在开发一个cs go投注网站，我买了这个来源，所以我不熟悉它，我的CSS和HTML技能不是最好的，但我有一个问题，你可以看到从显示获胜者的容器下方的图片是从主容器中出来的。

以下是该容器的css代码：

容器的实际类是名为＆＃34; winner-left＆＃34;

的类

 .winner {

    background: #737373;

    box-shadow: 0 -1px 0 #3c3c3c;
    padding: 12px 19px 12px 27px;
    position: relative;
    width: 100%;


}
.winner:before {
    content: '';
    position: absolute;
    top: -5px;
    left: 50%;
    width: 40px;
    height: 40px;
    margin-left: -21px;
    background: #696969;
    border: 1px solid #898989;
    box-shadow: -1px -1px 0 #202020, 1px -1px 0 #202020;
    -moz-transform: rotate(45deg);
    -ms-transform: rotate(45deg);
    -webkit-transform: rotate(45deg);
    -o-transform: rotate(45deg);
    transform: rotate(45deg);
    z-index: 3;
}
.winner:after {
    content: '';
    position: absolute;
    left: 50%;
    width: 60px;
    height: 60px;
    margin-left: -30px;
    top: 0;
    z-index: 4;
    background: #6e6e6e;
}
.winner-left {
    float: left;
    position: left;
    width: 100%;

}

我真的会得到一些帮助！如果需要更多代码或信息，请问我！
