如何将 CSS 应用于 HTML body 元素? [英] How to apply CSS to HTML body element?
问题描述
我正在努力摆脱这个:
document.body.className = "someclass";
我想在 CSS 中做到这一点.
I want to do this in CSS.
body.someclass {
.
.
.
}
不幸的是,我无法在 Firefox、chrome 中使用它.
unfortunately I am not able to get this working in Firefox, chrome.
我在这里做错了什么吗?有什么办法可以将 CSS 类应用于 body 吗?
Am I doing anything wrong here? Is there any way we could apply a CSS class to body?
推荐答案
你在那里做两件不同的事情.您的 JavaScript 实际上将类someclass"分配给您的 body 元素,而您的 CSS 正在样式化一个带有someclass"类的 body 元素,它不会将类分配给它,这不是CSS 的任务.您可以像这样在纯 (X)HTML 中执行此操作:
You are doing two different things there. Your JavaScript is actually assigning the class "someclass" to your body element, while your CSS is styling a body element with the class "someclass", it won't assign the class to it, that is not the task of CSS. You would do it in plain (X)HTML like this:
<body class="someclass">
