如何以编程方式将CSS定义应用于整个页面？ [英] How to programmatically apply CSS definitions to the whole page?

问题描述

我确定信息已经存在，但我找不到;对不起： - /

我想使用JavaScript创建CSS规则，并将它们应用到整个页面，就像它们在文档头部的样式元素中一样。我不想通过生成CSS文本 - 我想保持规则作为实体（JavaScript变量），我可以更改，从而改变以后的页面的外观。

解决方案

我找到了我想要的：http://www.javascriptkit.com/dhtmltutors/externalcss3.shtml 。

（感谢所有已经回答和评论的人，我想要的 - 最后发现，看到上面的链接 - 是一个实际的CSS规则对象，我可以动态地工作，就像HTML元素一样。答案接近，没有一个是正确的。）

I'm sure the information already exists, but I couldn't find it; sorry :-/

I want to create CSS rules using JavaScript, and apply them to the whole page, as if they were in a style element in the document's head. I don't want to do it by generating the CSS text - I want to keep the rules as entities (JavaScript variables) that I can change, thus changing the appearance of the page later on.

Any help will be most appreciated!

解决方案

I've found what I wanted: http://www.javascriptkit.com/dhtmltutors/externalcss3.shtml .

(Thanks to all who've answered and commented. What I wanted - and finally found, see the link above - was an actual CSS-rule object that I could work with dynamically, like with HTML elements. While some of the answers came close, none of them was exactly it.)
