Answer 2

@media screen and (min-width: 500px) {
    .submenu {
        /*This and this style when window-width is greater than 500px*/
    }
    }

@media screen and (max-width: 500px) {
    .submenu {
        /*This and this style when window-width is less than 500px*/
    }
    }

请添加您当前的样式和HTML代码以获得更详细的答案。

  nav li {
    float: left;
  }
}
