滑块图像顶部有多余的空间

时间：2018-08-09 12:19:13

标签： javascript html css

我在一个站点上实现了一个滑块，但是滑块上方有很多不需要的空间。正如您看到的自行车图像和菜单栏之间的空间一样，我想知道是否有任何方法可以删除该图像，以使自行车图像位于菜单栏下方。我尝试查看是否为滑块设置了高度，但我认为不是。

问题是，在CSS上，标头的高度为100vh ... 只需减少或删除金额即可。

header {
width: 100%;
/* height: 100vh; */
background: url(hero.jpg) no-repeat 50% 50%;
background-size: cover;
}
