css - 为什么在方向改变时不应用 css？

Question

我正在使用媒体查询。我的设备宽度为 360，高度为:640。实际上，当方向改变时，我添加了边框来检查是否应用了 css。

但是当我改变方向时它只显示红色边框。为什么不显示其他边框？

@media screen and (max-width: 360px), screen and (max-height: 640px)and (orientation: portrait) {
    .subcontent_h {
        height: 200px;
        overflow: auto;
        margin-top: 10px;
        border: 1px solid deeppink !important;
    }
}

@media screen and (max-width: 640px) , screen and (max-height: 360px)and (orientation: landscape) {
    .subcontent_h {
        height: 200px;
        overflow: auto;
        margin-top: 10px;
        border: 1px solid red !important;
    }
}

Answer 1

Order of Specification: As a last resort, when all other conflict resolution specifications cannot determine which style should take precedence, the last style specified will be the style used.

.subcontent_h{
    height: 200px;
    overflow: auto;
    margin-top: 10px; 
}

@media screen and (max-width: 640px) , screen and (max-height: 360px)and (orientation: landscape) {
    .subcontent_h {
        border: 1px solid red;
    }
}

@media screen and (max-width: 360px), screen and (max-height: 640px)and (orientation: portrait) {
    .subcontent_h {       
        border: 1px solid black;
    }
}
