如何更改bootstrap版本4按钮颜色

我可以通过更改bootstrap v4中的主题颜色来更改主按钮颜色.但它也会影响所有其他组件.如何在不影响主题颜色的情况下设置主按钮颜色？我不想设置品牌 - 初级并实现它.还有其他选择吗？

2018年Bootstrap 4.1更新

现在Bootstrap 4使用SASS,您可以使用mixins 轻松更改按钮颜色button-variant.由于您只想更改主要按钮颜色,而不是整个主要主题颜色,因此需要button-variant在SASS中使用mixins.您可以设置任何$mynewcolor和/或lighten()和darken()你想的百分比.

$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);
}

这个SASS编译成以下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)}
