问题描述
这可以用来改变CSS吗？不能看到很多关于它的w3。任何人都知道。
Can this be used to change CSS? Cant see much on w3 about it. Anyone know anything about it.
如果这个论坛/网站不是问问浏览器标准问题的地方，有人可能指向我正确的方向吗？
If this forum/site isnt the place for asking browser standard questions, can someone point me in the right direction?

推荐答案
是的，您可以使用setAttribute更改单个DOM元素的CSS，如下所示：
Yes, you can use setAttribute to change the CSS of a single DOM element, like so:
document.getElementById("something").setAttribute("style", "color: red;");
但是，我认为这是不好的做法。您可以按照Marius指出的方式修改样式表：
However, I believe it's bad practice. You can modify the stylesheet as Marius pointed out by doing:
document.styleSheets[0].cssRules[0].backgroundColor = "#FF0000";
或通过手动编辑HTML元素的样式属性，如：
or by manually editing the style attributes of HTML elements, like:
document.body.style.backgroundColor = "#FF0000";
我建议您查看，因为它具有功能强大，易于使用的工具来修改DOM元素的CSS。它很简单：
I would recommend looking into jQuery, as it has powerful and easy to use tools for modifying the CSS of DOM elements. It's as simple as:
$("#someID").css({"color": "red", "width": "100px"});
