html - 我怎样才能在响应中转换这个按钮？

Question

我正在尝试将此按钮转换为响应式，但我不知道如何，我希望此 4 按钮显示仅在移动设备上垂直对齐。我没有找到解决此问题的任何网站:(。感谢您的所有回答!

您可以在 .bottoni 上使用移动设备上的绝对位置来使菜单垂直居中，以实现响应式使用 media queries :

@media (max-width: 480px) {
    .bottoni {
        top: 50%; /* adjust to your needs */
        position: absolute;
        left: 0;
        right: 0;
    }
}
