sass – 如何创建_custom.scss以覆盖Bootstrap 4 alpha 6中的变量

我正在尝试自定义Bootstrap 4 alpha 6主题.我想将_variable.scss文件中的设置复制到_custom.scss以覆盖.但我没有在源代码中找到_custom.scss文件.如何在项目中添加此_custom.scss文件？ 我注意到你的问题 here, here和 here：

☐ Consider implementing a _custom.scss for easier, built-in variable overrides?

因此,因为你的Bootstrap 4没有附带_custom.scss文件,所以你只需要重新创建bootstrap / scss / _custom.scss.

然后编辑bootstrap / scss / bootstrap.scss到它应该是什么：

// Core variables and mixins
@import "variables";
@import "mixins";
@import "custom";

然后按照Customising variables

Bootstrap 4 [supposedly] ships with a _custom.scss file for easy overriding of default variables in /scss/_variables.scss. Copy and paste relevant lines from there into the _custom.scss file, modify the values, and recompile your Sass to change our default values. Be sure to remove the !default flag from override values.
