如何为不同的页面加载不同的CSS？ [英] how to load different css for different pages?
问题描述
我有一个设置的头文件
<！DOCTYPE html>
< html>
< head>
< meta charset =utf-8/>
< link href =/ includes / main.css =stylesheetmedia =all/>
< / head>
< body>
然后我有我的主体页面，我将有 main.html， project.html，contact.html ...等等
// php为我的身体加载不同的页面
< div> ...。
和页脚页。
< footer> ...
我的问题是如何交换css文件以适应我的主体页面的不同页面。页眉和页脚文件是模板，我不想在每次加载新页面时更改css文件。我该如何做到这一点？非常感谢！
一个简单的方法是使用名为basename的php函数。
如果您有3页main.php，project.php和contact.php，您可以根据所查看页面的名称加载不同的资源。
例如
echo;
<！DOCTYPE html>
< html>
< head>
< meta charset =utf-8/>
<？php if（basename（$ _ SERVER ['PHP_SELF']）=='main.php'）{？>
< link href =/ includes / main.css =stylesheetmedia =all/>
<？php}
elseif（basename（$ _ SERVER ['PHP_SELF']）=='project.php'）{
？>
< link href =/ includes / project.css =stylesheetmedia =all/>
<？php}？>
< / head>
< body>
I am trying to create different style sheet for my pages.
I have a set header file
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<link href="/includes/main.css" rel="stylesheet" media="all"/>
</head>
<body>
then I have my main body page, I will have main.html, project.html, contact.html …etc
//php load different pages for my body
<div>….
and a footer page.
<footer>…
My question is how to swap the css file to adapt different pages for my main body page. The header and footer files are the template and I don't want to change the css file every time I load a new page. How do I accomplish this? Thanks a lot!
One simple way of doing it is by using a php function called "basename".
If you have 3 pages main.php, project.php and contact.php, you can load different resources depending upon the name of the page you are viewing.
For example echo ;
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<?php if(basename($_SERVER['PHP_SELF']) == 'main.php'){ ?>
<link href="/includes/main.css" rel="stylesheet" media="all"/>
<?php }
elseif(basename($_SERVER['PHP_SELF']) == 'project.php'){
?>
<link href="/includes/project.css" rel="stylesheet" media="all"/>
<?php } ?>
</head>
<body>
