Explore the building blocks of Smart eLearning design with intelligent containers that use white space optimally. Objects placed in Fluid Boxes get aligned automatically so that learners always get fully responsive experience regardless of their device or browser. Use the pre-defined boxes in a responsive theme or draw your own. In the 2019 release of Adobe Captivate, Fluid Boxes get a productivity makeover – use the intuitive UI to control and customize your Fluid Boxes, view parent-child relations, distribute objects equally in a single click, define alignment properties in Static Fluid Boxes and more.
