推荐答案

2019年Bootstrap 4.1+更新

现在，Bootstrap 4使用SASS，您可以使用button-variant mixins轻松地仅更改按钮颜色.由于您只想更改主按钮的颜色，而不是整个主主题的颜色，因此需要在SASS中使用button-variant mixins.您可以设置任意的$mynewcolor和/或lighten()和darken()百分比.

Now that Bootstrap 4 uses SASS, you can easily change only the button color using the button-variant mixins. Since you only want to change the primary button color, and not the entire primary theme color, you need to use the button-variant mixins in SASS. You can set whatever $mynewcolor and/or lighten() and darken() percentages you'd like.

$mynewcolor:teal;

.btn-primary {
    @include button-variant($mynewcolor, darken($mynewcolor, 7.5%), darken($mynewcolor, 10%), lighten($mynewcolor,5%), lighten($mynewcolor, 10%), darken($mynewcolor,30%));
}

.btn-outline-primary {
    @include button-outline-variant($mynewcolor, #222222, lighten($mynewcolor,5%), $mynewcolor);
}

此SASS编译为以下CSS ...

This SASS compiles into the following CSS...

.btn-primary{color:#fff;background-color:teal;border-color:#005a5a}

.btn-primary:hover{color:#fff;background-color:#004d4d;border-color:#009a9a}
.btn-primary:focus,.btn-primary.focus{box-shadow:0 0 0 .2rem rgba(0,90,90,0.5)}
.btn-primary.disabled,.btn-primary:disabled{color:#fff;background-color:teal;border-color:#005a5a}
.btn-primary:not(:disabled):not(.disabled):active,.btn-primary:not(:disabled):not(.disabled).active,.show>.btn-primary.dropdown-toggle{color:#fff;background-color:#00b3b3;border-color:#000}
.btn-primary:not(:disabled):not(.disabled):active:focus,.btn-primary:not(:disabled):not(.disabled).active:focus,.show>.btn-primary.dropdown-toggle:focus{box-shadow:0 0 0 .2rem rgba(0,90,90,0.5)}

.btn-outline-primary{color:teal;background-color:transparent;background-image:none;border-color:teal}.btn-outline-primary:hover{color:#222;background-color:#009a9a;border-color:teal}
.btn-outline-primary:focus,.btn-outline-primary.focus{box-shadow:0 0 0 .2rem rgba(0,128,128,0.5)}
.btn-outline-primary.disabled,.btn-outline-primary:disabled{color:teal;background-color:transparent}
.btn-outline-primary:not(:disabled):not(.disabled):active,.btn-outline-primary:not(:disabled):not(.disabled).active,.show>.btn-outline-primary.dropdown-toggle{color:#fff;background-color:#009a9a;border-color:teal}
.btn-outline-primary:not(:disabled):not(.disabled):active:focus,.btn-outline-primary:not(:disabled):not(.disabled).active:focus,.show>.btn-outline-primary.dropdown-toggle:focus{box-shadow:0 0 0 .2rem rgba(0,128,128,0.5)}
