扩展 Bootstrap 4 和 SASS [英] Extending Bootstrap 4 and SASS

问题描述

由于 Bootstrap 只是最近才正式发布，因此一些页面仍然需要处理(https://getbootstrap.com/docs/4.0/extend/ - 待办事项:整个页面).

As Bootstrap was only recently officially released some of the pages still need to be worked on ( https://getbootstrap.com/docs/4.0/extend/ - todo: this entire page).

我对 sass/scss 完全陌生，所以这可能很容易.我想要做的是创建一个完整的类，该类适用于引导程序中的所有预配置样式.

I'm entirely new to sass/scss so this might be easy. What I want to do is create an entire class that works with all the pre-configured styles in bootstrap.

例如，我如何制作一个 .drop-shadow 类，它可以实现所有颜色(以及最终的其他设置)，例如 .drop-shadow-primary、.drop-shadow-secondary 等等.

For example, how could I make a .drop-shadow class, that would implement all the colors (and eventually other settings) like .drop-shadow-primary, .drop-shadow-secondary and so on.

推荐答案

可以通过像这样迭代 Bootstrap 4 theme-colors() 映射来完成...

It could be done by iterating the Bootstrap 4 theme-colors() map like this...

@each $color, $value in $theme-colors {
  .drop-shadow-#{$color} {
    box-shadow: 3px 3px 3px $value;
  }
}

另见:如何更改引导程序原色?
