我试图close在图像的右上角(不是框中)从bootstraps sprite 定位一个图标.我从一个有效的例子中得到了这个,但它对我不起作用.它总是在盒子外面和屏幕的右下角结束.
我怎样才能做到这一点？我已经设置了一个小提琴,但无法想象如何在那里获得精灵.你能帮我吗？

这个例子可以拍摄任何高度的图像。
转<i class="delete">成<div>
<img>用新的删除 div包裹
给.image:beforeamin-height: 150px;并删除固定高度.image
适用position: relative于.delete
将删除按钮应用到带有.delete:after或放置另一个伪元素<i>以使其具有交互性。
