(SCSS) 我的媒体查询无法正常使用 display: flex;

Question

我正在使用 SCSS 尝试创建一个响应式网站。我正在使用 Koala 编译我的代码，并且我有一个 styles.scss 正在导入我的其他部分样式表。更改宽度时，某些样式确实在我的网站上动态工作，但使用我的显示：事情并没有改变到我想要的样子。

我尝试将媒体查询更改为嵌套在自身内部，但没有任何工作正常。

styles.scss

@import "reset";

@import "variables";

// @media only screen and (min-width: 1em) {
@import "small-default";
// }

//35em is also 560px (if basefont is 16px)
@media only screen and (min-width: 560px) {
@import "medium";
}

//64em is also 1028px (if basefont is 16px)
@media only screen and (min-width: 1028px) {
@import "large";
}

_medium.scss （我只是想对布局做一个简单的方向改变，但没有任何效果。）

footer {

    .info {
        flex-direction: row;
    }
}

Answer 1

应该是

.footer {
  footer {
     .info {
        flex-direction: row;
    }
  }
}

或

.footer footer .info {
    flex-direction: row;
}

如果您想像在 medium.scss 中那样调用它
