如何在另一张图片上叠加10x10像素的图片？ [英] How can i overlay an 10x10px image on top of another image?

问题描述

我在我的网站上有一个用户头像。简单图片标记：

I have a user avatar on my website. Simple image tag:

<img src="foo.jpg" class="userphoto" width="48" height="48" alt="">

现在，我想要浮动

这表示用户已通过Facebook身份验证。

This is to signify that the user is authenticated to Facebook.

我该如何做？ CSS样式在图像标签上，或者我将必须有一个独立的div与绝对定位？

How can i do this? CSS styling on the image tag, or will i have to have a seperate div with absolute positioning?

不需要是透明的或任何东西，只需要定位

Doesn't need to be transparent or anything, just needs to be positioned exactly in the top-left corner.

当然，我不能只是物理修改图像，因为我需要确定是否基于Facebook状态动态地覆盖图像。但我希望动态添加一个css类。

Of course i cant just physically modify the image, as i need to determine whether to overlay the image dynamically based on the Facebook status. But i was hoping to dynamically add a css class.

任何想法？

ANSWER:

使用这两个答案的组合。使用div代替其他图片。

Got it working with a combination of both answers. Used a div instead of another image.

HTML：

<div class="foo">
   <div class="fboverlay"></div>
   <a>
      <img src="foo.jpg" class="userphoto" width="48" height="48" alt="">
   </a>
</div>

CSS：

.foo
{
   position: absolute;
   top: 0;
   right: 0;
}

.fboverlay
{
    background-image: url('/image/facebook/logo.gif');
    position: absolute;
    z-index: 1;
    top: 10px;
    left: 10px;
    width: 10px;
    height: 10px;
}

感谢您的帮助。

推荐答案

我知道我没有使用你想要的精确尺寸，但这里是一个工作的例子。 （您需要父级.main_photodiv作为主照片的尺寸。）

I know I'm not using the exact dimensions you wanted, but here's a working example for you. (You would need the parent ".main_photo" div to be the dimensions of the main photo.)

.main_photo{
    position:relative;
    width:80px;
    height:80px
}
.inlay{
    position:absolute;
    top:5px;
    right:5px
}

<div class="main_photo">
    <img src="https://secure.gravatar.com/avatar/?s=200&d=mm&r=pg" />
    <img class="inlay" src="https://www.rit.edu/news/lib/views/public/images/dateline_images/facebook_icon.gif" />
</div>
