推荐答案
将bootstrap css覆盖到您自己的css ，例如。 bootstrap有.btn-danger并使用红色颜色。所以你可以做的是，改变这个按钮的颜色。
创建你自己的.css文件并将它引用到你的html，并在其中编写bootstrap重写的css类。
现在，回答你的问题就好了，
Override the bootstrap css to your own css, e .g. bootstrap has.btn-dangerand usesredcolor for it. So what you can do is, change the color for this button.
Create your own .css file and reference it to your html, and write the bootstrap overridden css classes in it.
Now, answer to your question would be something like,
.navbar
{
background-color:#f44;
color:#fff;
border:0;
}
我刚刚覆盖了bootstrap的导航栏风格到我自己的风格。
确保你不要在任何bootstrap的样式表中进行更改。 jQuery。创建具有相同名称类的自定义css，并根据您的意愿覆盖css规则。
希望清楚:)

I just overridden the bootstrap's navbar style to my own style.
Make sure that you don't make changes in any of the bootstrap's stylesheets & jQuery. Create you custom css with the same name class and override the css rule to your wish.
Hope that's clear :)

颜色由3个（或4个）组成部分组成：红色，绿色，蓝色（最终是透明度）。
获得给定颜色的相反颜色的公式为：
A color is composed of 3 (or 4) components : red, green, blue (and eventually transparency).
The formula to get the 'opposite' color of a given color is:
Color originalColor;
Color oppositeColor = Color.FromARGB(
originalColor.A, // Here I keep the same transparency value
255 - originalColor.R,
255 - originalColor.G,
255 - originalColor.B
);
希望这有帮助。
Hope this helps.
