改变CSS类定义 [英] changing CSS class definition

问题描述

假设我有这个类：

.MyClass{background:red;}

此类适用于多个div。我想通过更改MyClass中定义的颜色将背景颜色更改为橙​​色。

This class applies to several divs. I want to change the color of the background to orange by changing the color defined in MyClass.

现在，我知道我可以做< c $ c> $（'。MyDiv'）。css（'background'，'orange'）;

Now, I know I could do $('.MyDiv').css('background', 'orange');

这个：我如何改变CSS类定义，使MyClass元素现在有 background：orange; ？我想要能够将几种CSS颜色属性从一种颜色更改为另一种颜色。

But my question is really this: how do I change the CSS class definition so that MyClass elements now have background:orange;? I want to be able to change several CSS color properties from one color to another.

谢谢。

实际上改变你的样式表是相当具有挑战性的。更容易，但您可以切换不同的样式表，这可能已经足够您的目的。请参见如何使用jQuery切换CSS样式表？。

Actually altering your stylesheet is pretty challenging. Much more easily, though, you can switch out your stylesheet for a different one, which may be sufficient for your purposes. See How do I switch my CSS stylesheet using jQuery?.

要实际更改样式表内容，请如何在运行时更改/删除CSS类定义？将让你开始。
