html - Firefox 我的 td 文本未在单元格中间对齐

Question

它在 ie 和 chrome 上运行良好。我尝试了一些简单的修复，但不确定为什么我尝试过的没有任何效果。

    table {
    *border-collapse: collapse; /* IE7 and lower */
    border-spacing: 0;
    width: auto;
    margin-left:auto; 
    margin-right:auto;
    margin-top: 1%;    
}

.bordered {
    border: solid #ccc 0px;
    -moz-border-radius: 6px;
    -webkit-border-radius: 6px;
    border-radius: 6px;
    -webkit-box-shadow: 0 1px 1px #ccc; 
    -moz-box-shadow: 0 1px 1px #ccc; 
    box-shadow: 0 1px 1px #ccc;
    background-color:#ffffff;         
}

                </table>

我也很好奇是否没有在文本上指定标签什么是 CSS 中考虑的文本？

Answer 1

他们没有居中，因为你有

.bordered td, .bordered th {
     text-align: left;
}

将其更改为text-align: center;（或text-align: right;......不清楚您在问什么，将每个文本对齐到 的中间，将每个文本对齐<td>到 的中间<table>，或其他东西）以使其工作。

编辑

现在您编辑了您的帖子，很明显您的意思是垂直对齐。

好吧，在这个答案的开头打开小提琴（您未修改的代码），它们是垂直对齐的。如果你设置

.bordered td, .bordered th {
     height: 50px;
}

它们仍然对齐。

问题在于您没有向我们展示的 CSS，而不是您展示的 CSS。

如果我不得不猜测，我会责怪自定义文本框。
