Problems positioning text DIV over image DIV with CSS
提问by Josh Graham
I'm creating a webpage for my photography and basically I'm trying to create div boxes that contain the images, with a div for text displayed over the image. For some reason I cannot work out how to make the text div position from the image div. For example, currently "top: 8%;" positions the text 8% from the top of the page not the top of the image div, despite the fact that the text div is withing the image div in the code and positioned relatively.
我正在为我的摄影创建一个网页，基本上我正在尝试创建包含图像的 div 框，并在图像上显示一个文本 div。出于某种原因，我无法弄清楚如何从图像 div 制作文本 div 位置。例如，目前“最高：8%；” 尽管文本 div 在代码中与图像 div 一起并且相对定位，但将文本从页面顶部而不是图像 div 顶部定位 8%。

Just set the z-indexin your CSS. Higher numbered elements appear above lower numbered elements. While you can just give elements contiguous whole numbers; generally, you'll want to provide large gaps between lower and higher elements in case you need to add additional elements or change the layering of elements.
只需z-index在您的 CSS 中设置。编号较高的元素出现在编号较低的元素上方。虽然你可以只给元素连续的整数；通常，您需要在较低和较高的元素之间提供较大的间隙，以防您需要添加其他元素或更改元素的分层。
