Scrolling block changes

31 March 2026

Squarespace are rolling out a replacement Scrolling Block from 31 March 2026.

This change is technical in nature, so you shouldn’t see any functional changes at this time. However, these changes will allow the Scrolling Block to support a host of improvements, later in 2026.

If you use any custom code that targets Scrolling Blocks, your code may break. This is because the block properties, previously stored in a JSON script tag (<script class="Marquee-props" type="application/json">), have been moved to data attributes on the .Marquee class element.
