how to copy past bootstrap css classes from one element to another? is this feature available in BSS?
You can copy them with ctrl + c and paste with ctrl + v same as any other app. If the classes are applied using the Options pane, they will then show up in dark blocks in the styles line. You can still copy those directly same as any others.
If you have classes applied or styles applied using the Options pane, there is 3 little buttons in the top right corner of each section of the Options pane that allow you to copy using the first button and switch to the other component and the second button should be lit up to paste with.
Hope that helps
