Ability to show elements "floating center" or "floating bottom"
We are testing XD as a replacement for visually spec'ing on the web. It would be great if we could specify screen positions for elements that either are floating center vertically within a column, floating 30% above the bottom of a column, 30px from the bottom of a column, etc. Essentially, it would be helpful to be able to communicate position as a container percentage, as well as a way to communicate that this element's positioning is relative to the top, middle, or bottom of an element.
Thanks for your feedback! We currently don’t reference to center and bottom, but we do use a fixed viewport. This means that your object can be 30px off the bottom of the viewport and will stay there if the fixed element selection is turned on. Similarly, if you position your object at the center of your viewport, it’ll stay there if the position is set. While the way you think of it is different than your developer, it should at least look the same.
