css - 如何使表响应类名？

Question

我有这个媒体:

@media
only screen and (max-width: 760px),
(min-device-width: 768px) and (max-device-width: 1024px)  {

    /* Force table to not be like tables anymore */
    table, thead, tbody, th, td, tr {
        display: block;
    }

    /* Hide table headers (but not display: none;, for accessibility) */
    thead tr {
        position: absolute;
        top: -9999px;
        left: -9999px;
    }

    tr { border: 1px solid #ccc; }

    td {
        /* Behave  like a "row" */
        border: none;
        border-bottom: 1px solid #eee;
        position: relative;
        padding-left: 50%;
    }

    td:before {
        /* Now like a table header */
        position: absolute;
        /* Top/left values mimic padding */
        top: 6px;
        left: 6px;
        width: 45%;
        padding-right: 10px;
        white-space: nowrap;
    }

}

此媒体影响所有 table 元素。现在我怎样才能在我想要的 table 上使用这个媒体？

为您想要的表添加类或 ID。例如，我将 class="test" 添加到您想要的表中。你的 CSS 是这样的

@media
only screen and (max-width: 760px),
(min-device-width: 768px) and (max-device-width: 1024px)  {

    /* Force table to not be like tables anymore */
    .test, .test thead, .test tbody, .test th, .test td, .test tr {
        display: block;
    }

    /* Hide table headers (but not display: none;, for accessibility) */
    .test thead tr {
        position: absolute;
        top: -9999px;
        left: -9999px;
    }

    .test tr { border: 1px solid #ccc; }

    .test td {
        /* Behave  like a "row" */
        border: none;
        border-bottom: 1px solid #eee;
        position: relative;
        padding-left: 50%;
    }

    .test td:before {
        /* Now like a table header */
        position: absolute;
        /* Top/left values mimic padding */
        top: 6px;
        left: 6px;
        width: 45%;
        padding-right: 10px;
        white-space: nowrap;
    }

}
