Question

请告诉我为什么此代码会重复页面底部Dash Task的背景图片，以及为什么第三个<span class="price">$1000 p/night</span>在单击底部<div>之前仍然可见？< / p>

$("div").on('click', function() {
  $(this).toggleClass('show-description');
});

Answer 1

所有段落在自己的父亲下都可见，但第一个和第二个在下一个框下面并且不可见，但不是最后一个。最后一个div，他的段落<div class="plane"><p>...</p></div>创建了一个可见空间。

将overflow:hidden;添加到div flintstones / hobbit / plane进行修复。

Answer 2

只需使用background-repeat: no-repeat即可。如此简单而又如此强大。
