我有一个 ASP.NET 4.5 应用程序，我必须在其中使用一系列模态窗口。第一个模态窗口允许用户输入一些数据，而第二个模态窗口用于确认目的。由于某种原因，第二个模态窗口不会居中对齐。我试过 {position: absolute; | 重新定位模式=“无”| X="0" Y="0" | JS .add_shown } 它似乎没有工作。也许我的设计有问题。我修改了我的 CSS、HTML 和模态属性，但没有成功。我绝对需要一双额外的眼睛。任何帮助将不胜感激。提前致谢。

我弄清楚了问题所在。我需要在我的 CSS 中添加以下 4 行：

    .confirm-panel
    {
        background-repeat: no-repeat;
        background-image: url('../Images/CustomImage/AppConfirm.png');

        margin-right: auto !important;
        margin-left: auto !important;
        right: auto !important;
        left: auto !important;

        font-family: Arial;
        font-size: 9pt;
        color: #336699;
    }
