1、设置meta <meta name=“viewport” content=“width=device-width, viewport-fit=cover”>
2、设置外层盒子高度100%
@supports ((height: constant(safe-area-inset-top)) or (height: env(safe-area-inset-top))) {
body {
/* 适配齐刘海*/
padding-top: constant(safe-area-inset-top);
padding-bottom: env(safe-area-inset-top);
padding-bottom: constant(safe-area-inset-bottom); /* iOS 11.0 */
padding-bottom: env(safe-area-inset-bottom); /* iOS 11.2 */
}
}
