Sample Code on StackBlitz

我一直试图用纯css来实现这一点,以便在我的角度代码中只处理那些数据和屏幕转换(routerlinks)。我把样式设计留给CSS和其他库(即棱角砌体)

问题是 .feed-header 坐在过滤器后面,所以你需要设置一个 z-index

.masonry-item
.feed-container
.feed-header {
  position: absolute;
  width: 100%;
  padding: 10px;
  align-items: center;
  display: flex;
  z-index: 9;
}

另外,如果你想让文本对比,你可以设置它为白色悬停(以对比黑暗过滤器)。您可以使用:

.masonry-item
.feed-container:hover
.feed-header {
  color: white;
}

Here is a StackBlitz demo

This stackblitz should work

我所做的就是把球顶上图像并将其作为SASS添加到CSS文件中:

ngxMasonryItem {
  .feed-text {
    color: white;
    z-index: 9999;
  }
  &:hover {
    img {
      filter:  blur(2px) brightness(50%)
    }
  }
}

(删除以前使用的过滤器)

在HTML中,声明顺序很重要,也是如此 z-index
