How Did Reddit Create a Thinner Scrollbar That Only Appears on Hover?
When browsing Reddit, you might notice that the scrollbars on the site are not the traditional size you’re accustomed to. They’re slimmer and only appear when you hover over them. So, how exactly did Reddit achieve this effect, and how can you incorporate similar functionality into your own web projects?
The CSS Behind Custom Scrollbars
The secret to Reddit’s sleek scrollbar lies in CSS styling. CSS offers the ability to customize scrollbars through properties specifically designed for this purpose. These properties let you modify the width, color, and even the visibility of scrollbars.
Here’s a quick guide on how you can implement similar scrollbars in your code:
“`css
/ Targeting WebKit browsers, like Chrome and Safari /
::-webkit-scrollbar {
width: 8px; / Set the scrollbar width /
}
::-webkit-scrollbar-thumb {
background-color: rgba(0, 0, 0, 0.5); / Customize the thumb color /
border-radius: 4px; / Add rounded corners /
}
::-webkit-scrollbar-thumb:hover {
background-color: rgba(0, 0, 0, 0.8); / Change color on hover for better visibility /
}
“`
Making the Scrollbar Visible Only on Hover
To make the scrollbar appear only when hovering, you can use CSS’s opacity property combined with a transition for a smooth effect:
“`css
/ Initially hide the scrollbar /
::-webkit-scrollbar {
opacity: 0;
transition: opacity 0.3s;
}
/ Show the scrollbar on hover /
element:hover ::-webkit-scrollbar {
opacity: 1;
}
“`
By applying these simple styles to your web elements, you can achieve a sleek, modern look similar to what Reddit utilizes. As a note, keep in mind that these styles are specifically for WebKit browsers like Chrome and Safari. For broader compatibility including Firefox, additional vendor prefixes may be needed.
For more advanced customizations, you may want to explore JavaScript solutions or libraries that offer even more control over scrollbar behavior.
Conclusion
Reddit’s use of CSS artistry for scrollbars enhances both the aesthetics and user experience on their platform. By utilizing some basic CSS properties, you too can implement stylish and functionally attractive scrollbars in your projects, enhancing the overall look and feel of your website.

2 responses to “Reddit’s Implementation of a Slim Hover-Visible Scrollbar”
Reddit’s approach to a thinner scrollbar that’s only visible on hover is likely achieved using a combination of CSS properties, particularly ones that are widely supported in modern browsers. Here’s a breakdown of how such a scrollbar can be designed:
1. Leveraging
::-webkit-scrollbarCSS Pseudo-elementsTo create custom scrollbars, you can use the
::-webkit-scrollbarpseudo-elements. These allow you to modify the default scrollbar’s appearance in browsers like Chrome, Safari, and the newer versions of Edge. Here’s a basic outline:“`CSS
/ Entire scrollbar /
::-webkit-scrollbar {
width: 8px;
height: 8px;
}
/ Track of the scrollbar /
::-webkit-scrollbar-track {
background: transparent;
}
/ Handle of the scrollbar /
::-webkit-scrollbar-thumb {
background: #888;
border-radius: 4px;
transition: opacity 0.3s;
opacity: 0; / Initially hidden /
}
/ Handle on hover /
::-webkit-scrollbar-thumb:hover {
background: #555;
opacity: 1; / Visible on hover /
}
“`
2. Handling Visibility on Hover
Reddit makes the scrollbar thumb visible only when hovered over. This can be achieved using
opacityandtransitionproperties. By default, you can set theopacityof the thumb to0and change it to1when the scrollbar is hovered. You can do this by adding an opacity transition to the scrollbar thumb:css.your-scrollable-element:hover ::-webkit-scrollbar-thumb {
opacity: 1; /* Make the thumb visible on hover */
}
3. Ensuring Cross-Browser Compatibility
While
::-webkit-scrollbarallows fine-tuning in Webkit-based browsers, Firefox, for instance, uses a different mechanism. You can use thescrollbar-widthandscrollbar-colorproperties for some basic styles in Firefox:“`css
.your-scrollable-element {
scrollbar-width: thin;
scrollbar-color: #888 transparent; / Thumb color and track color /
}
.your-scrollable-element:hover {
scrollbar-color: #555 transparent; / Thumb color on hover /
}
“`
4. Applying the Styles
To ensure these styles work correctly, it’s important to apply them to the specific elements where you need custom scrollbars. For example:
“`html
<div
This post highlights an interesting approach to scrollbar design, which can significantly enhance user experience by balancing aesthetics and functionality! One aspect worth considering is accessibility. While a slim and discreet scrollbar may look modern, it could pose challenges for users with visual impairments or those who rely on keyboard navigation.
To address this, it might be beneficial to ensure that the scrollbar maintains sufficient contrast and size for visibility, even when not hovered over. Additionally, providing alternative navigation means—such as keyboard shortcuts or visible scroll indicators—can make a significant difference in usability.
It could also be intriguing to explore how JavaScript libraries like `SimpleBar` or `Perfect Scrollbar` can offer more customizable and accessible scrollbar experiences across different browsers. These libraries provide smoother scrolling and more detailed configurations, which may complement what can be achieved with CSS alone.
Overall, I appreciate the insights shared here, and I look forward to seeing how others adapt these techniques while considering inclusivity in their Web Design practices!
