This is (yet) another feature that makes Blocked shine. Mobile Behaviors is an algorithm built into blocked that allows your columns to behave as you tell them to, in mobile device resolutions.
Mobile Behaviors only work on IPhone-like resolutions, both in Landscape and Portrait orientation.
What are they then ? When having a 4-Column layout on certain components (that have Mobile Behavior integrated), you can tell the component to split the columns in Portrait and/or Landscape mode.
Blocked’s footer has mobile behaviors enabled for Mobile Landscape mode. Resize your browser and see!
Also, the Homepage 3 demo has it enabled. Check it out!
