要让转圈圈的图变粗，您可以使用 border 属性来设置边框的粗细。修改后的代码如下所示：
.decorate1 {
position: absolute;
width: 300px;
height: 300px;
background: url('@/assets/images/cockpit/common-digit1.webp');
background-size: 300px 300px;
animation: numbg 3s linear infinite;
/* 添加边框样式 */
border: solid 5px;
@keyframes numbg {
0% {
filter: hue-rotate(0deg);
}
50% {
filter: hue-rotate(60deg);
}
100% {
filter: hue-rotate(0deg);
}
}
}
通过添加 border 属性，并设置其为 solid 边框样式和 5px 的宽度，您可以使转圈圈的图形变得更加粗细。根据需要，您也可以调整边框的宽度值。
