Two kinds of scrolling text — pick the one you need
"Scrolling text" is really two jobs, and this page does both. Most people want the bio-scroll trick: a block of repeated text that overflows a profile's fixed-height bio box so the box has to scroll. A smaller group wants a literal animated marquee — a ticker that slides across a screen — for a website, a forum signature, or a stream overlay.
Marquee Banner → an embeddable CSS animation that physically moves across the screen.
The tab at the top of the page switches between them. Bio mode is the front door — plain text solves the job in seconds. Reach for marquee mode only when you actually need motion on a page you control.
How the bio scroll trick works
A profile bio is a box with a fixed height. If the text you paste is taller than that box, the box scrolls to reveal the rest. That is the whole trick — there is no special "scroll" character.
Use Fill to platform and the tool sets the repeat count to just clear a chosen field's limit (Instagram bios hold about 150 characters; TikTok about 80 — always approximate, since platforms change them). If your blank lines collapse when you save, switch to a visible divider — a line, dot, or star row — so every line carries a real character and survives. You can also restyle the whole block in any Unicode font before copying; the letters change, the divider glyphs stay.
Embed a scrolling marquee on a site or OBS overlay
Marquee mode builds a self-contained snippet — a little CSS plus HTML — that you paste into a page you control. It uses uniquely-named classes and its own keyframes, so it never clashes with the rest of your page, and it bundles no external fonts or files.
— Forum signature: paste it wherever raw HTML is allowed.
— OBS overlay: save the snippet as an
.html file and add it as a Browser source.
The animation scrolls a doubled track for a seamless loop, pauses on hover, and — unlike the old approach — automatically stops for visitors who prefer reduced motion. It is the modern replacement for the deprecated <marquee> tag: same effect, standards-based, portable.
