html - Youtube 背景视频

Question

<分区>

Answer 1

这是因为您的 iFrame 被页面中的其他元素覆盖了。它不会得到你所做的点击。

This答案建议两种方法。

Like you said you have to change the z-index of every child of body except the iframe.

body > * {
z-index : 2 !important;
}

#youtube_bg {
z-index : 1;
}

Or you change the z-index of body and html to -1, the iframe to 0 and the content keeps at 1 or auto.

html, body {
z-index : -1;
}
#yotube_bg {
z-index : 0;
}
