Custom Scrollbars Mixin

Scrollbars are one of those UI components that are present on almost every page of the internet, yet we (developers) have little to no control over it. Some browsers give us the ability to customize their appearance but for most browsers including Firefox it just is not possible.

Still, Chrome and Internet Explorer (yes) make it possible for us to define custom styles for scrollbars. However the syntax horribly complex, and of course, definitely not standard. Welcome to the proprietary world. This is why you might want to have a little mixin to easily customize your scrollbars. Right?

/// Mixin to customize scrollbars
/// Beware, this does not work in all browsers
/// @author Hugo Giraudel
/// @param {Length} $size - Horizontal scrollbar's height and vertical scrollbar's width
/// @param {Color} $foreground-color - Scrollbar's color
/// @param {Color} $background-color [mix($foreground-color, white, 50%)] - Scrollbar's color
/// @example scss - Scrollbar styling
///   @include scrollbars(.5em, slategray);
@mixin scrollbars($size, $foreground-color, $background-color: mix($foreground-color, white,  50%)) {
  // For Google Chrome
  ::-webkit-scrollbar {
      width:  $size;
      height: $size;

  ::-webkit-scrollbar-thumb {
      background: $foreground-color;

  ::-webkit-scrollbar-track {
      background: $background-color;

  // For Internet Explorer
  body {
    scrollbar-face-color: $foreground-color;
    scrollbar-track-color: $background-color;


@include scrollbars(.5em, slategray);

See the Pen Sass mixin for scrollbar styling by Hugo Giraudel (@HugoGiraudel) on CodePen.

Going further

On both browsers, there are many more options than just color and size. However they are often overlooked so I don't think it is worth overcrowding the mixin with these options. Feel free to build a more advanced mixin with extra options.
