// Form control focus state

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