Question

我正在使用react ant-design，并且使用@media查询进行样式设置，但它一直抛出下面给出的错误

#btn {
          ^
    Media definitions require block statements after any features
          in /home/osh/WebstormProjects/ant-design-kickstart/src/styles/styles.less (line 69, column 8)
     @ ./src/styles/styles.less 2:14-142 21:1-42:3 22:19-147
     @ ./src/index.js
     @ multi (webpack)-dev-server/client?http://localhost:8081 (webpack)/hot/dev-server.js react-hot-loader/patch ./src/index.js
     Failed to compile.

我在下面提供了相关文件

------------ styles.less文件---------------

@仅媒体屏幕和（最大宽度：768px）{

#btn {

    width: 50%;
    margin-top: 200px;
    align-self: center;
}

Button {
    width: 1000%;
    marginBottom: '25px'
}

Input {
    align-self: center;
    width: 250px;
}

h4 {
    color: #5400ff;
}

.appDashCard {
    background: #fff;
    padding: 10%;
/*//minHeight: 280px;*/
    align-content: center;
}

}

@仅媒体屏幕和（最小宽度：768像素）{

#btn {
    width: inherit;
    margin-right: 30px;
    margin-left: 400px;
    margin-top: 30px;
}

h4 {
    color: #ff2600;
}

.appDashCard {
    background: #fff;
    padding: 24px;
    minHeight: 280px;
}



.selectBox {
    width: 100%;
}

}

Answer 1

这通常表示语法错误。请查看“按钮”。它具有一个名为'marginBottom'的属性，将其重命名为margin-bottom-bottom，请在语句后也添加一个分号（尽管这没有什么区别）。另外，您应该将“按钮”重命名为“按钮”，将“输入”重命名为“输入”。

React antdesign @media查询不起作用
