Frequently Asked Questions

Webkit-based browsers (Chrome, Safari, Edge, Opera, Brave) support extensive scrollbar customization via ::-webkit-scrollbar pseudo-elements. Firefox supports limited customization through scrollbar-width and scrollbar-color properties. Internet Explorer and older browsers have no support for scrollbar styling.

macOS has a system setting that hides scrollbars by default when not actively scrolling. Go to System Settings → Appearance → Show scroll bars and select "Always" to see custom scrollbar styles. This affects all browsers on your Mac.

Yes! You can manually replace hex colors in the generated CSS with rgba() or hsla() values to achieve transparency. For example, rgba(0, 0, 0, 0.25) creates a semi-transparent dark thumb. The color picker outputs hex, but the final CSS is fully editable.

No, custom scrollbar CSS has negligible impact on performance. The styles are purely visual and rendered by the browser's compositing engine. However, extremely complex styles (like animated gradients) on very long pages might have a minor effect. Stick to solid colors and simple border-radius for best results.

For Firefox, set scrollbar-width: none;. For Webkit browsers, use: ::-webkit-scrollbar { display: none; } or set width to 0. This hides the scrollbar while preserving scroll functionality — useful for horizontal scroll containers and mobile-friendly designs.

Yes! Use ::-webkit-scrollbar for both, ::-webkit-scrollbar:horizontal for horizontal only, and ::-webkit-scrollbar:vertical for vertical only. You can set different widths and colors for each direction. Firefox does not support directional scrollbar styling.

Absolutely! In the generated Webkit CSS, replace the thumb's background property with a gradient value like background: linear-gradient(180deg, #667eea, #764ba2);. This creates stunning gradient scrollbars that work beautifully in Chrome, Safari, and Edge.

Custom scrollbar styles do work inside iframes — simply include the CSS within the iframe's document. For Shadow DOM, Webkit pseudo-elements do not cross shadow boundaries, so you'll need to apply the styles inside the shadow root. Firefox's scrollbar properties inherit normally within shadow DOM.
