Some content should show up for some while – and then disappear, or then shrink to some small size? That’s the purpose of the new component SIZEANMIATIONAREA.
Any content can be placed inside – and any content can be placed around. You define the from-width/height, the to-width/height and the duration after which the component should change its size. And after it is e.g. hidden you can trigger to re-show the component any time. Please take a look into the “News” section of the demo workplace.
