dependencies: Adding Bower out of nixpkgs...
dependencies: Adding Bower out of nixpkgs Usually bower would be installed globally, so it seems to be appropriate to use the one out of the nixpkgs so that we don't have to pin a specific version ourselves.

// Generate a customized focus state and for any input with the specified color,
// which defaults to the `@input-border-focus` variable.
//
// We highly encourage you to not customize the default value, but instead use
// this to tweak colors on an as-needed basis. This aesthetic change is based on
// WebKit's default styles, but applicable to a wider range of browsers. Its
// usability and accessibility should be taken into account with any change.
//
// Example usage: change the default blue border and shadow to white for better
// contrast against a dark gray background.
