CSS scrollbar Property

❮ Prev Next ❯

The scrollbar set of CSS properties is a proprietary style hook letting designers create custom themes for the browser's native scrollbars.

Now, it is exposed behind the -webkit vendor prefix.

The -webkit-scrollbar set of properties consists of seven different pseudo-elements that, together, comprise a full scrollbar UI element. These seven pseudo-elements are the following:

::-webkit-scrollbar
::-webkit-scrollbar-button
::-webkit-scrollbar-track
::-webkit-scrollbar-track-piece
::-webkit-scrollbar-thumb
::-webkit-scrollbar-corner
::-webkit-resizer

Initial Value	auto
Applies to	Scrolling boxes.
Inherited	Yes.
Animatable	Discrete.

DOM Syntax	-

Syntax

scrollbar: ::-webkit-scrollbar-button | ::-webkit-scrollbar-track | ::-webkit-scrollbar-track-piece | ::-webkit-scrollbar-thumb | ::-webkit-scrollbar-corner | ::-webkit-resizer

Example of the scrollbar property:

    <style>
      html {
        height: 100%;
        overflow: hidden;
      }
      body {

Here's an example of how to create a vertical sidebar in HTML and CSS:

<!DOCTYPE html>
<html>
  <head>
    <title>Title of the document</title>
  </head>

  <style>
    /* Style for the sidebar container */
    .sidebar {
      height: 40%; /* Set the height of the sidebar to fill 40 % of the screen */
      width: 200px; /* Set the width of the sidebar */
      position: fixed; /* Make the sidebar fixed */
      top: 0; /* Position the sidebar at the top of the screen */
      left: 0; /* Position the sidebar on the left side of the screen */
      background-color: #c3c3c3; /* Set the background color of the sidebar */
      overflow-x: hidden; /* Hide horizontal scrollbar */
    }

    /* Style for the links inside the sidebar */
    .sidebar a {
      display: block; /* Display links as block elements */
      padding: 16px; /* Add some padding to the links */
      color: #000; /* Set the color of the links */
      text-decoration: none; /* Remove underline from links */
    }

    /* Add a hover effect to the links */
    .sidebar a:hover {
      background-color: #ddd;
    }

    /* Style for the main content area */
    .main-content {
      margin-left: 200px; /* Set the left margin to the width of the sidebar */
      padding: 20px; /* Add some padding to the main content */
    }
  </style>

  <body>
    <div class="sidebar">
      <a href="#">Link 1</a>
      <a href="#">Link 2</a>
      <a href="#">Link 3</a>
      <a href="#">Link 4</a>
      <a href="#">Link 5</a>
    </div>

    <div class="main-content">
      <!-- Your main content here -->
    </div>
  </body>

In this example, we have created a sidebar container with a fixed position on the left side of the screen. We have set the width and height of the sidebar container, as well as the background color and overflow property to hide the horizontal scrollbar. Inside the sidebar container, we have added links that are styled as block elements and have a hover effect when the mouse is over them.

The main content area is positioned to the right of the sidebar by setting the left margin to the width of the sidebar. This ensures that the main content does not overlap with the sidebar.
