## AI overview

This article explains the development of Squarespace's Fluid Engine, a new drag-and-drop editor designed to improve the usability and predictability of page layout. It describes user research into moving, resizing, and aligning blocks, the limitations of the existing Layout Engine, and the decision to develop a new system so those actions would not affect other blocks.
