When you set up Constraints and Resizing in your designs on Sketch, Figma, or Adobe XD and then publish them to Zeplin, you can access these details using the Constraints Widget on the right panel.

When you select a parent or child layer, Zeplin visualizes the constraints' settings with the related information next to it.

If the layer has auto height or auto width properties on some of its sides, Zeplin animates the visualization under the Constraints Widget.
