Question

我的页面上设置了一个div，当用户将鼠标悬停在div上时，该div会显示一个叠加层。在其他网站上，例如在这里：http://www.elpassion.com有一个非常好的效果，也简化了div背后的背景。我似乎无法像我所看到的那样有效地工作，并且正在寻求一些支持和指导。

Answer 1

我稍微改变了你的小提琴，以便当你悬停图像时你的背景图像会略微缩放，如elpassion-example中所示。

您可以使用以下css缩放/拉伸div的背景图像：

.portfolio-project-image:hover {
    background-size: 102% 102%;
    background-repeat: no-repeat;
    background-position: center center;
}
