| docs | Customization options | Customize Bootstrap with Sass variables, easily toggling global preferences with a quick recompile. | getting-started |
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 the included Gruntfile as needed.
Customizing variables
Bootstrap 4 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.
For example, to change out the background-color and color for the <body>, you'd do the following:
{% highlight scss %}
// Bootstrap overrides
//
// Copy variables from _variables.scss to this file to override default values
// without modifying source files.
$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
You can find and customize these variables for key global options in our _variables.scss file.
