我有以下规则:
@media only screen and (min-device-width : 320px) and (max-device-width : 480px)
@media only screen and (min-width : 321px) /* Smartphones (landscape) */
@media only screen and (max-width : 320px) /* Smartphones (portrait) */
@media only screen and (min-width: 768px) /* tablets and desktops */
如何在不影响其他规则的情况下捕捉平板肖像?
