我已经下载了bootstrap源代码，但又不想使用company = serializers.HyperlinkedRelatedField(
many=False,
read_only=True
)
（170kb）和bootstrap.css（138kb）
我只使用button.js（5.09kb），只想要按钮相关的CSS。
我可以自己手动获取所有与按钮相关的css，但在bootstrap.min.css中浏览9000行时非常耗时。
一些手动css的例子：
bootstrap.css存档中的scss文件夹中包含所有单独的样式表
例如，在.btn{color:#00bc8c; border-color:#00bc8c}
.btn:hover,.btn.active{color:#fff; background-color:#00bc8c}
.btn{padding:0.5rem 1rem;font-size:1.171875rem;}
.btn-group{display:inline-flex;}
.btn-group .btn{margin-left:-1px}
.btn-group>.btn:not(:last-child){border-top-right-radius:0;border-bottom-right-radius:0}
.btn-group>.btn:not(:first-child){border-top-left-radius:0;border-bottom-left-radius:0}
.btn input[type="radio"]{position:absolute;clip:rect(0,0,0,0);}
：
_button-group.scss它得到了我想要的所有按钮相关的东西。
所以我尝试使用http://beautifytools.com/scss-compiler.php但是我收到了这个错误：
.btn-group {
> .btn:first-child {
margin-left: 0;
}
// Reset rounded corners
> .btn:not(:last-child):not(.dropdown-toggle),
> .btn-group:not(:last-child) > .btn {
@include border-right-radius(0);
}
> .btn:not(:first-child),
> .btn-group:not(:first-child) > .btn {
@include border-left-radius(0);
}
}
网站确实声明＆＃34;如果你的scss代码有，那么在@import语句中输入完整的URL。＆＃34;
所以我需要引用更多的全局scss信息。我假设开发所有这些bootstrap东西的人有一个很好的程序来很好地开发所有这些scss并单独组织。如果有人知道如何编译按钮scss，请告诉我。我唯一的想法是＆＃34;引用＆＃34;他们自己，就是将所有其他scss添加到同一个源文件中，但那时只需编译所有源代码。请帮忙。
答案 0 :(得分：1)
在@import "functions";
@import "variables";
@import "mixins";
@import "buttons";
@import "button-group";
内删除您不想要的导入。 （除了那些你还需要的人）

我刚刚在git上检查了他们的代码。 - ＆gt; https://github.com/twbs/bootstrap-sass/blob/master/assets/stylesheets/bootstrap/_button-groups.scss
正如您所看到的那些@include语句 - 这些是使用的mixin，它们来自其他文件。
还有一个占位符@extend .btn-xs等，你需要这些，以便你的scss可以正确地转换为CSS。
您可以找到这里使用的mixins和占位符，或者包含整个文件。
