我正在尝试将命名空间写入外部css(实际上是两个单独的文件)。当我在浏览器上运行该文件时,它将不使用声明的命名空间。我认为该文件正在调用css文件,但它没有应用命名空间样式

思想?
答案 0 :(得分:5)
在你的XHTML中:
您的标记格式不正确:
您的XML声明应首先出现,然后是您的doctype声明:
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
您的部分<link />
代码未正确关闭,应为:
<link rel="stylesheet" href="movies.css" type="text/css" />
<link rel="stylesheet" href="actors.css" type="text/css" />
您的页面必须由服务器提供为application/xhtml+xml
。典型的服务器不知道您正在提供XHTML,因此他们将其作为text/html
发送。浏览器无法将text/html
文件视为XML,因此它们不会将CSS应用于您的自定义XML元素。
如果您使用PHP,只需将其添加到XHTML文件的顶部即可:
<?php header('Content-Type: application/xhtml+xml'); ?>
或者在ASP中添加:
<% Response.ContentType = "application/xhtml+xml"; %>
您还应该有一个附带的元标记,但您的页面无需验证,浏览器无论如何都会忽略它:
<meta http-equiv="Content-Type" content="application/xhtml+xml; charset=utf-8" />
您可以在this answer中找到关于UAs将XHTML视为HTML标记汤的简短历史课程,以便更好地理解这一点。
在你的CSS中:
这是font-weight: bold
,而不是font-style: bold
。
这是font-style: italic
,而不是font-style: italics
。
确保将@namespace
语句放在样式表的开头。来自spec:
任何
@namespace
规则必须遵循所有@charset和@import规则,并在样式表中所有其他未忽略的at-rules和规则集之前。
但是,尽管如此,为什么不将演员和电影放入他们自己的XML文件中,然后使用XSLT将它们转换为熟悉的实际XHTML ?
