Question

我有一个奇怪的问题。颜色不会在表格中显示：我做错了什么？

＆＃34;危险＆＃34;据我所知，班级应该在这里工作。

<table class="table table-bordered">

<thead>
    <tr>
        <th>ID</th>
        <th>Hardware (navn)</th>
        <th>Map</th>
    </tr>
</thead>

<tbody>

<tr class="danger">
    <td class="danger col-md-1">
        33
    </td>

    <td class="danger col-md-2">
        Something
    </td>

    <td class="danger col-md-1">
        Something else
    </td>

    <td class="danger col-md-2">
        DATE
    </td>

    <td class="danger">
        Description.........
    </td>
</tr></tbody></table>

Answer 1

对于使用text-danger的文字着色，使用bg-danger进行背景着色。

据我所知，Bootstrap中没有danger类。

Answer 2

正如引导程序color documentation所解释的那样。

班级：bg-danger - 将背景颜色更改为红色。

类：text-danger - 将字体颜色更改为红色。

Answer 3

你使用错误的类试试这个：

<td class="bg-danger  col-md-1">
    33
</td>

Answer 4

如果您使用bootstrap 4，则正确的类为table-danger，请参阅this
