实际上，我有两个带有动态内容的页脚。这就是我使用 jquery 使子页脚和主页脚保持粘性的原因。 现在页脚粘性正在工作，但在窗口调整大小时，主页脚的高度增加。请看脚本。我想，我对脚本有疑问。我在代码底部添加了脚本。

最佳答案
根据评论编辑:
- 完全删除 JS 并将以下 CSS 属性添加到您的动态页脚:
bottom: 46px; --> 你的静态页脚高度
下面的片段:
html {
position: relative;
height: 100%;
}
body {
/* Margin bottom by footer height */
}
.footer {
position: absolute;
bottom:46px;
width: 100%;
/* Set the fixed height of the footer here */
background-color: #000;
text-align: center;
color: #fff;
}
.footer-bottom {
padding: 3px 0;
position: absolute;
bottom: 0;
background-color: green;
text-align: center;
width: 100%;
