javascript - 旋转木马上方的间隙

Question

我讨厌弄乱 Stack Overflow，但我似乎无法在此处更新我的原始问题 - Issue with div floating on top of carousel . JSFiddle 不正确。

我遇到了一些麻烦: http://jsfiddle.net/myoozik/U6bV8/

如果您看一下旋转木马上方，就会发现一个巨大的缺口。这是在旋转木马顶部添加黑色覆盖 div 的结果。

关于如何消除这个差距，也就是它是如何产生的，有什么想法吗？

HTML

Answer 1

由于存在具有一定高度、宽度和背景颜色的 #overlay-div Div，因此出现黑色框。如果您将 display:none 设置为它，空格和黑框将消失。

下面是CSS

#overlay-div {
    background-color: #000000;
    display: none;
    height: 200px;
    left: 100px;
    position: relative;
    top: 300px;
    width: 200px;
    z-index: 999;
}
