::-webkit-scrollbar

Non-standard: This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The ::-webkit-scrollbar CSS pseudo-element affects the style of an element's scrollbar when it has scrollable overflow.

The scrollbar-color and scrollbar-width standard properties may be used as alternatives for browsers that do not support this pseudo-element and the related ::-webkit-scrollbar-* pseudo-elements (see Browser compatibility).

Note: If scrollbar-color and scrollbar-width are supported and have any value other than auto set, they will override ::-webkit-scrollbar-* styling. See Adding a fallback for scrollbar styles for more details.

CSS Scrollbar Selectors

You can use the following pseudo-elements to customize various parts of the scrollbar for WebKit browsers:

  • ::-webkit-scrollbar — the entire scrollbar.
  • ::-webkit-scrollbar-button — the buttons on the scrollbar (arrows pointing upwards and downwards that scroll one line at a time).
  • ::-webkit-scrollbar:horizontal{} — the horizontal scrollbar.
  • ::-webkit-scrollbar-thumb — the draggable scrolling handle.
  • ::-webkit-scrollbar-track — the track (progress bar) of the scrollbar, where there is a gray bar on top of a white bar.
  • ::-webkit-scrollbar-track-piece — the part of the track (progress bar) not covered by the handle.
  • ::-webkit-scrollbar:vertical{} — the vertical scrollbar.
  • ::-webkit-scrollbar-corner — the bottom corner of the scrollbar, where both horizontal and vertical scrollbars meet. This is often the bottom-right corner of the browser window.
  • ::-webkit-resizer — the draggable resizing handle that appears at the bottom corner of some elements.

Accessibility concerns

Authors should avoid styling scrollbars, as changing the appearance of scrollbars away from the default breaks external consistency which negatively impacts usability. If styling scrollbars, ensure there is enough color contrast and touch targets are at least 44px wide and tall. See Techniques for WCAG 2.0: G183: Using a contrast ratio of 3:1 and Understanding WCAG 2.1 : Target Size.

Examples

Styling scrollbars using -webkit-scrollbar

CSS

css
.visible-scrollbar,
.invisible-scrollbar,
.mostly-customized-scrollbar {
  display: block;
  width: 10em;
  overflow: auto;
  height: 2em;
  padding: 1em;
  margin: 1em auto;
  outline: 2px dashed cornflowerblue;
}

.invisible-scrollbar::-webkit-scrollbar {
  display: none;
}

/* Demonstrate a "mostly customized" scrollbar
 * (won't be visible otherwise if width/height is specified) */
.mostly-customized-scrollbar::-webkit-scrollbar {
  width: 5px;
  height: 8px;
  background-color: #aaa; /* or add it to the track */
}

/* Add a thumb */
.mostly-customized-scrollbar::-webkit-scrollbar-thumb {
  background: #000;
}

HTML

html
<div class="visible-scrollbar">
  <h3>Visible scrollbar</h3>

    Etiam sagittis sem sed lacus laoreet, eu fermentum eros auctor. Proin at
    nulla elementum, consectetur ex eget, commodo ante. Sed eros mi, bibendum ut
    dignissim et, maximus eget nibh. Phasellus blandit quam turpis, at mollis

<div class="invisible-scrollbar">

<div class="mostly-customized-scrollbar">

    And pretty tall<br />
    thing with weird scrollbars.<br />
    Who thought scrollbars could be made weird?

Adding a fallback for scrollbar styles

You can use a @supports at-rule to detect if a browser supports the standard scrollbar-color and scrollbar-width properties, and otherwise use a fallback with ::-webkit-scrollbar-* pseudo-elements. The following example shows how to apply colors to scrollbars using scrollbar-color if supported and ::-webkit-scrollbar-* pseudo-elements if not.

HTML

html
<div class="scrollbox">
  <h1>Yoshi</h1>
  <p>
    Yoshi is a fictional dinosaur who appears in video games published by
    Nintendo. Yoshi debuted in Super Mario World (1990) on the SNES as Mario and
    Luigi's sidekick.
  </p>
  <p>
    Throughout the mainline Super Mario series, Yoshi typically serves as
    Mario's trusted steed.
  </p>
  <p>
    With a gluttonous appetite, Yoshi can gobble enemies with his long tongue,
    and lay eggs that doubly function as projectiles.
  </p>
</div>

CSS

css
/* For browsers that support `scrollbar-*` properties */
@supports (scrollbar-color: auto) {
  .scrollbox {
    scrollbar-color: aquamarine cornflowerblue;
  }
}

/* Otherwise, use `::-webkit-scrollbar-*` pseudo-elements */
@supports selector(::-webkit-scrollbar) {
  .scrollbox::-webkit-scrollbar {
    background: aquamarine;
  }
  .scrollbox::-webkit-scrollbar-thumb {
    background: cornflowerblue;
  }
}

Result

In the example below, you can scroll the bordered box vertically to see the effect of styling the scrollbar.
