html - 响应式固定宽度3列布局，在台式机和移动设备中具有全宽抽屉

我有一个3列的图块自适应设计，其中移动设备为1列，桌面为3列，每个图块都有一个内容抽屉，需要扩展屏幕的整个宽度（带有蓝色背景）。

我在下面的笔中有一个工作模型，但是不能让抽屉伸展整个宽度吗？

不知道它是CSS还是在进行移动优先设计时是否有更好的HTML布局，并且它是否有效，只是不在桌面/更宽的视图中。

Codepen：

function openDrawer(tile) {

    var drawer = $(tile).attr("drawer");

    if ( $(tile).hasClass("ESGActive") ){ // Already is active?
         $(".ESGTile").removeClass("ESGActive");
         $("#" + drawer).slideUp();
    } else {
      // Get all tiles with class="ESGActive" and remove it
      $(".ESGTile").removeClass("ESGActive");

      // Get all elements with class="ESGDrawer" and hide them
      $(".ESGDrawer").slideUp();

      // Show the current tab drawer, add "active" class to the button
      $("#" + drawer).slideDown();
      $(tile).addClass("ESGActive");a
    }
}

最佳答案

你在这里
我在CSS的末尾添加了此代码

.body {
    position: relative;
}
.ESGDrawer {
    position: absolute;
    top: 247px;
    left: 0px;
    width: 100%;
}
.x{

    position: inherit;
}

我为您的每个col-xs-12 col-md-4 div添加新的类名
