我试图将#box1 定位在#table1 下，我尝试移动它，但它没有移动。我究竟做错了什么。我是 CSS 新手。

编辑：我把我的html

    <!DOCTYPE html>
         <html lang="en">
         <head>
    <title>Assignment 1</title>
    <meta charset="utf-8">
    <style>

    html{
        background: #afc2df;
        }
    #box1{

        position fixed;
        border: 120px;
        border-style: groove;
        border-radius:35px;
        width: 505px;
        length: 75px;
        margin-left: 85px;
        z-index: 5;

        }
        this is the table I want to move 

    #table1{

        position fixed;
        background: #00FFFF;
        margin-left: 118px;
        top: 160px;
        z-index: 6;
           }

    </style>
    </head>


    <body>

    <b></b><h1><b><i><font face="impact" color="red">Name</font> </i></b></h1>

    <b></b><h2><b><i><font face="impact" color="red">Number</font> </i></b></h2>

    <table border="3" id="table1">
            <tbody><tr>
                <th colspan="2">WEB PAGE ELEMENTS</th>


            </tr>
            <tr>
                <th>Html</th>
                <td><font face="Candara" color="black">Marks beginning and ending of a web page (closing tags needed)</font></td>

            </tr>
            <tr>
                <th>Head</th>
                <td><font face="Candara" color="black">Used to enclose elements not apart of the main page (closing tags needed)</font></td>

            </tr>
            <tr>
                <th>Title</th>
                <td><font face="Candara" color="black">Included in the &lt;head&gt; section, appears in the title bar of the browser (closing tags needed)</font></td>

            </tr>
            <tr>
                <th>Body</th>
                <td><font face="Candara" color="black">Includes content that is visible in the browser (closing tag needed)</font></td>

            </tr>
            <tr>
                <th>Meta</th>
                <td><font face="Candara" color="black">Allows passage of information about the page to user agents(self-closing tag)</font></td>

            </tr>
        </tbody></table>

这是 CSS 和我的 html。

我真的很想在这方面做得很好，并感谢您的帮助。

我做了一些修改来清理你的代码。预先警告：你需要把这件事简化，不要直接把这个任务交给你的导师，除非他们除了视觉输出之外什么都不知道（如果他们立即离开那所大学并自学成才！）。不要过度依赖 CSS 2 级position属性，如果他们没有教你 CSS 1 级，float那么你可能会永久无法胜任地编写 CSS。

如果您想学习如何正确使用 CSS，请从基础开始...

话虽如此，这可以满足您的要求，页面内容会滚动，而巨大的边框分割元素则不会。
