// Form control focus state
//
// Generate a customized focus state and for any input with the specified color,// which defaults to the `@input-focus-border` 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.
