作为任务的一部分,我开发了一个网站。由于我是 html/css 的新手,我无法从我的代码中找出一些问题。分配规范说屏幕尺寸应该是一定的尺寸,以便大多数浏览器可以打开它并且用户不应该体验任何滚动活动。所以我使用 div 来划分整个页面以适应大小。但是,容器(在我的代码中名为“box”)设置在浏览器主体的左侧,我必须将其设置为居中,但我不知道如何修复它。谁能给我一些帮助,请,谢谢。
我的 HTML:
<!DOCTYPE html>
<html>
<head>
<title>habibe Naby</title>
<link rel="stylesheet" href="Websystems.css">
</head>
<body>
<div id="box">
<div id="header">
<img id="image" src="spring.jpeg">
<p id="text">Welcome to My Homepage</p>
</div>
<div id="under">
<div id="upper">
<div id="leftbar">

</ul>

<div id="rightbar">
