如何在打印媒体时显示div，其他时间隐藏？

Question

我想用它只打印

#section-to-print

:

@media print {
    body * {
        visibility: hidden;
    }
    #section-to-print, #section-to-print * {
        visibility: visible;
    }
    #section-to-print {
        position: absolute;
        left: 0;
        top: 0;
    }
}

如何扩展它以在屏幕上显示时隐藏

#section-to-print

？ 换句话说，它只有在打印介质时才可见。

Answer 1

将其设置为visibility:hidden，然后@media print可以覆盖它。

#section-to-print, #section-to-print * {
    visibility: hidden;
}
@media print {
    body * {
        visibility: hidden;
    }
    #section-to-print, #section-to-print * {
        visibility: visible;
    }
    #section-to-print {
        position: absolute;
        left: 0;
        top: 0;
    }
}
