html - 如何将 bootstrap scss 编译成 css

Question

我已经下载了 bootstrap源代码，但不想使用 bootstrap.css (170kb) 和 bootstrap.min.css (138kb)

中的所有 css

我只使用 button.js (5.09kb) 并且只想要与按钮相关的 css。

我自己可以手动获取所有与按钮相关的 css，但是遍历 bootstrap.css 中的 9000 行非常耗时。

一些手动CSS的例子:

.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);}

存档中有一个 scss 文件夹，里面装满了所有单独的样式表

例如，在_button-group.scss中:

.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);
  }
}

它有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但我得到这个错误:

Error: no mixin named hover
       Backtrace:
        stdin:16
        on line 16 of stdin
>>     @include hover {
   -------------^

该站点确实声明“如果您的 scss 代码有这些，请在 @import 语句中输入完整的 url。”

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 的人都有一个很好的程序来很好地开发所有这些 scss 并单独组织。如果有人知道我如何编译按钮 scss，请告诉我。我自己“引用”它们的唯一想法是将所有其他 scss 添加到同一源文件，但那样只会编译所有源文件。请帮忙。

Answer 1

在 bootstrap.scss 中删除不需要的导入。 (除了那些你仍然需要的)

@import "functions";
@import "variables";
@import "mixins";
@import "buttons";
@import "button-group";

现在 bootstrap.css 只有 500 行按钮样式!
