我只想放大背景图像，但是它覆盖了标题，overflow: hidden不起作用

CSS

.board {
    background-image: url(img/bg-1.jpg);
    background-size: cover;
    background-position: center;
    transform: scale(2);
    overflow: hidden;
}

Answer 1

删除变换：scale（2）;从CSS然后显示正常。

.board {
background-image: url('https://cdn.pixabay.com/photo/2017/08/30/01/05/milky-way-2695569_960_720.jpg');

background-position: center;
overflow: hidden;
