html - 背景图像在缩放时覆盖标题

我只希望背景图像被缩放，但它覆盖了标题，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

移除变换:scale(2);从 css 然后它显示正常。

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

overflow: hidden;
