的效果。怎樣才能達到這種效果？純粹使用CSS還是需要JS？我一直在嘗試使用溢出來複製它，但它不工作一樣。

你應該能夠用CSS postioning財產fixed的幫助實現這一目標。

#main { 
 
    background-color: aqua; 
 
} 
 
#container { 
 
    width: 40%; 
 
    float: left; 
 
    top: 20px; 
 
    position: fixed; 
 
} 
 
#side-panel { 
 
    float: right; 
 
    width: 50%; 
 
    background-color: white; 
 
} 
 
#footer { 
 
    clear: both; 
 
    background: green; 
 
    width: 100%; 
 
    position: relative; 
 
    height: 100vh; 
 
}

<div id="main"> 
 
    <div id="container"> 
 

 
    This is fixed 
 

 
    </div> 
 

 
    <div id="side-panel"> 
 

 
    Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has 
 
    survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing 
 
    software like Aldus PageMaker including versions of Lorem Ipsum. It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less 
 
    normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem 
 
    ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like). Contrary to popular belief, Lorem Ipsum is not simply random text. 
 
    It has roots in a piece of classical Latin literature from 45 BC, making it over 2000 years old. Richard McClintock, a Latin professor at Hampden-Sydney College in Virginia, looked up one of the more obscure Latin words, consectetur, from a Lorem 
 
    Ipsum passage, and going through the cites of the word in classical literature, discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero, written 
 
    in 45 BC. This book is a treatise on the theory of ethics, very popular during the Renaissance. The first line of Lorem Ipsum, "Lorem ipsum dolor sit amet..", comes from a line in section 1.10.32. The standard chunk of Lorem Ipsum used since the 1500s 
 
    is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form, accompanied by English versions from the 1914 translation by H. Rackham. Lorem

在我嘗試我基本由左側面板fixed和右側面板浮動的權利。

但是我不知道這是否是最好的解決方法。
