为多个登录页优化CSS

在WordPress的附加CSS中使用CSS，我试图在三个登录页中隐藏一个表单。将CSS添加为

body.page-id-4077 .bg-tan-darker.color-white-base {
    display: none;
}

在做下面的事情时有效，但不起作用

body.page-id-4077 .bg-tan-darker.color-white-base, body.page-id-4082 .bg-tan-darker.color-white-base, body.page-id-4086 .bg-tan-darker.color-white-base, {
    display: none;
}

请告诉我，我需要遵循的正确方法是什么，以便为上述多个页面包含CSS。

从代码中删除最后一个逗号：

body.page-id-4077 .bg-tan-darker.color-white-base, 
body.page-id-4082 .bg-tan-darker.color-white-base, 
body.page-id-4086 .bg-tan-darker.color-white-base {
    display: none;
}
