当我打开模态视图时，标题图像出现在模态前面，我该如何阻止它？

标签： javascript jquery html css

This is an picture of the issue我已经设置了一个功能，可以在单击站点徽标时打开登录模式视图。

模态视图正确打开，但有三个元素忽略模态代码的规则。

两个站点徽标图像和站点菜单当前选项卡显示在模式上方，不受影响站点其余部分的背景不透明度的影响。

我试图解决这个问题，我将元素的z-index设置为与我希望它们出现的位置相对应，但这没有效果。 因为我对编码相当缺乏经验，所以我无法找到可能出错的地方。

（请注意，我还没有将我的图片导入小提琴，因为没有它们，效果仍然可见）

要激活模态，请单击左上角的框。

我希望有人在这里可以看到我出错的地方，因为这个问题困扰了我好几天了！

只需使用ID标头关闭</div>，就可以了：

<div id="header">

             <img id="headerBackground" src="siteImages/tiltchair.jpg">

             <img id="Logo" onclick="document.getElementById('id01').style.display='block'" align="middle" src="siteImages/final.png" alt="Logo">

             <img id="Text" align="middle" src="siteImages/TWText.png" alt="Logo">
 </div>

这是通过使用bootstrap来完成的。我建议你阅读bootstrap documentation，通过例子充分理解它。他们的网站上有很多简单的例子，但here你可以找到很多可以探索和玩的引导代码片段。

在下面的示例中，我有意识地区分了部分代码，以便您可以轻松阅读用于创建此模式的结构。有些课程不言而喻：modal-content, modal-header, modal-title, modal-body等等。

模态形式的结构，如下所示：

  • 按钮触发模态
  • 模态内容
  • 模态标题（带文字和关闭按钮）
  • 模态身体（带表格）

我希望它有所帮助
