## Customizing variables
|
|
|
|
Every Sass variable in Bootstrap 4 includes the `!default` flag, meaning you can override that default value in your own Sass even after that original variable's been defined. Copy and paste variables as needed, modify the values, remove the `!default` flag, and recompile.
|
|
|
|
For example, to change out the `background-color` and `color` for the `<body>`, you'd do the following:
|
|
|
|
{% highlight scss %}
|
|
$body-bg: $gray-dark;
|
|
$body-color: $gray-light;
|
|
{% endhighlight %}
|
|
|
|
Do the same for any variable you need to override, including the global options listed below.
|
|
|
|
## Global options
|
|
|
|
Customize Bootstrap 4 with our built-in custom variables file and easily toggle global CSS preferences with new `$enable-*` Sass variables. Override a variable's value and recompile with `npm run test` as needed.
|
|
|
|
You can find and customize these variables for key global options in our `_variables.scss` file.
