我想让网站调整高度和宽度以适应任何屏幕，我的意思是它必须根据屏幕尺寸改变大小。我制作了这个代码，它在我的电脑上看起来很完美，但是当我在我的工作电脑上打开我的网站时，屏幕较小，我看到网站上的所有东西都没有在正确的位置，我的意思是搞砸了。
代码：
<html>
<head><title>overview</title>
<link rel="stylesheet" type="text/css" href="style/style.css">
</head>
<body>
<?php
@session_start();
if(isset($_SESSION ['id'])) {
print ("
<div id='nav'><a href='logout.php'>logout</a></div>
<iframe src='mainpage.php' name='sidemenu' id='mp'></iframe>
<iframe src='sidemenu.php' name='mainpage' id='sm'></iframe>
<footer style='background: #4276A4;height: 38px;border: none;'</footer>
");
} else { echo "<meta http-equiv='refresh' content='0,login.php'>";}
?>
</body>
</html>
css代码：
@font-face {
font-family: "JF Flat Regular";
src: url('fonts/JF/JF-Flat-regular.eot');

我无法添加评论。所以回答它。
你没有让自己的风格做出回应。定义不同屏幕尺寸的样式。
对于Ex：
@media (max-width: 1024px) and (max-height:768px) { //for screen with max-width 1024px apply this style
.banner {
width:100px;
height:150px;
}
}
@media (max-width: 880px) {//for screen with max-width 880px apply this style
.banner {
width: 60px;
height: 90px;
}
}
在上面的代码中，根据屏幕大小，不同的样式应用于'banner'类。
或使用Bootstrap响应，如@ User8889所示。
