It's not just transparency but also fill and stroke color.
When applying transparency to a group of elements the transparency property is not shown. Therefore the properties of a group should be passed to each layer inside that group.
Please see my attached file.
Would be great to show the values much like Zeplin, especially for background blur. As of current, I keep having to tell the iOS devs the values which is counter-productive.
We are not showing the blur attributes , since background blur doesn't translate to direct css. Would you like us show the values or would you prefer to pass on such layers as assets to the developer?
