css：溢出滾動添加額外的填充
[英]css: overflow scroll adds extra padding
問題描述
我有以下 html & css 代碼：
<!DOCTYPE html>
<html>
<head>
<style type="text/css">
html, body {
margin: 0;
}
#container{
width:100vw;
height:100vh;
background-color: green;
}
#left-bar{
position: absolute;
width: 300px;
height: 100vh;
background-color: red;
overflow: scroll;
}
</style>
</head>
<body>
<div id="container">
<div id="left-bar" >
</div>
</div>
</body>
</html>
它給：
左側欄內有一個填充，我不明白為什么以及如何刪除它。
我嘗試過的事情：
- 添加
padding: 0;在左欄上，它不起作用（與!important一樣）。 - 使用檢查器了解填充的來源。 我沒有找到。
- 移除
overflow: scroll。 它有效，但我希望左欄有行為overflow: scroll
如何刪除左側欄中的此填充？
編輯：該錯誤以完全相同的代碼消失了。
現在使用相同的代碼：
我做了什么：
- 重啟電腦，bug依舊
- 添加 css 代碼以設置滾動條樣式
- 刪除我添加的代碼->錯誤消失了
我不懂為什么...

您看到的是一個空滾動條。 設置溢出overflow: auto 。 如果內容溢出，這只會顯示滾動條。
<,DOCTYPE html> <html> <head> <style type="text/css"> html: body { margin; 0: } #container{ width;100vw: height;100vh: background-color; green: } #left-bar{ position; absolute: width; 300px: height; 100vh: background-color; red: overflow; auto; } </style> </head> <body> <div id="container"> <div id="left-bar" > </div> </div> </body> </html>

您可能會考慮使用一個做最小滾動條的插件（也許更簡單的條）。 還可以考慮只做overflow-y:scroll以獲得更可接受的外觀。 您還可以更改滾動槽 colors 的colors

No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure?</p> </section> </div>
Webkit CSS3列為其容器添加了額外的填充。
