47//
48// We highly encourage you to not customize the default value, but instead use
49// this to tweak colors on an as-needed basis. This aesthetic change is based on
50// WebKit's default styles, but applicable to a wider range of browsers. Its
51// usability and accessibility should be taken into account with any change.
52//
53// Example usage: change the default blue border and shadow to white for better
54// contrast against a dark gray background.
