How to override bootstrap variables in sass?
提问by SUNGRAIZ FARYAD
I was trying to customize a Bootstrap 4. I want to copy settings from _variable.scss file to _custom.scss to override. But I didn't find _custom.scss file in source code. How do I add this _custom.scss file in my project?
我试图自定义 Bootstrap 4。我想将设置从 _variable.scss 文件复制到 _custom.scss 以进行覆盖。但是我在源代码中没有找到 _custom.scss 文件。如何在我的项目中添加这个 _custom.scss 文件？

Bootstrap 4 is a big hit. They have completely rewritten it. So, You can override the variables very easily. Just create a _custom-variables.scssfile and import it before _variables.scssfile in bootstrap.scssas shown below.
Bootstrap 4 大受欢迎。他们已经完全改写了它。因此，您可以非常轻松地覆盖变量。只需创建一个 _custom-variables.scss文件并将其导入到bootstrap.scss 中的_variables.scss文件之前，如下所示。
Copy the variable which you want to override, paste it in _custom-variables.scssand change the value as you want. Also remove the !default attribute. Compile it again and done. The !default attribute is reverse of !important. It will take the value of previously declared variable.
复制要覆盖的变量，将其粘贴到_custom-variables.scss并根据需要更改值。还要删除 !default 属性。再次编译并完成。!default 属性与 !important 相反。它将采用先前声明的变量的值。
