Generated CSS
Compatible Webkit + Firefox/* Scrollbar styles will appear here */Frequently Asked Questions
Modern Chrome, Edge, Safari (Webkit/Blink) fully support
::-webkit-scrollbar pseudo-elements. Firefox supports scrollbar-width and scrollbar-color. This tool generates both sets for maximum cross-browser compatibility.Mobile browsers often hide scrollbars or use overlay scrollbars that ignore custom styling. The generated CSS mainly affects desktop environments, but it won't break mobile layouts.
Change the Target Selector field to any valid CSS selector, e.g.,
.sidebar, #chat-box, or body for the whole page. The generated code will use that selector.Webkit provides full control over every part (thumb, track, buttons, corners). Firefox currently only allows
scrollbar-width (auto, thin, none) and scrollbar-color (thumb track). This tool outputs both for the best experience.Make sure the target element actually has scrolling content (overflow: auto/scroll). Also check that browser settings haven't overridden scrollbars (some accessibility modes force native styles).
