试图让一个粘性页脚工作，但它一直与正文标记内容重叠。我尝试过在.css中更改正文和页脚的位置，但没有成功。
CSS
body
{
background-color: #7f7f7f;
color:white;
font-family: "courier New", Perpetua Titling MT;
position:relative ;
}
footer
{
background-color: #7f7f7f;
color:white;
font-family: "courier New", Perpetua Titling MT;
font-size: 1em;
margin-top:auto;
overflow:hidden;
bottom: 0;
left: 0;
position: fixed;
right: 0;
}
HTML
<footer>
<nav>
<ul class = "footer">
<li><a href = "gallery.html">Gallery</a></li>
<li><a href = "about.html">About Us</a></li>
<li><a href = "contact.html">Contact Us</a></li>
<li><a href = "sitemap.html">Sitemap</a></li>
</ul>
</nav>
</footer>
任何帮助都将不胜感激！提前感谢！
您的输出不清楚，但如果粘性位置正在使用您的属性作为示例
