Marquee Scroll

Marquee Scroll is a Drupal 10/11 module that allows site builders to display text fields or custom blocks as smoothly scrolling marquee banners. It replaces the old HTML tag with a modern, CSS/JS-driven solution using requestAnimationFrame for better performance and accessibility.

Features
Field Formatter: Apply to text fields (string, string_long, text, text_long) to render their values as scrolling marquees.

Configurable Options:

Scrolling speed (px/s)

Gap between repeated text (px)

Direction: Left, Right, Up, Down

Custom Block: Add a standalone scrolling text block anywhere on your site.

Smooth Animation: Uses modern JavaScript and CSS for a fluid, GPU-friendly scrolling effect.

No Deprecated Tags: Ensures compliance with HTML5 and accessibility standards.
