Working with component css files in workspaces in chrome with angular cli 6 project
@Kayce Basques, the technical writer of Chrome DevTools commented on a question similar to this one, saying:
DevTools technical writer here. The workflow that benshabatnoam posted is the best we've got. Set up a Workspace and then edit your files from the Sources panel. Editing from Elements panel > Styles pane works on basic projects, but has trouble with frameworks (such as Angular) that use sourcemaps and do a lot of build transformations. Sucks, I know, but I recall that we've looked into it in-depth and our hands are tied until sourcemap usage is standardized.
Unfortenatly the answer to your question is NO, we can't (as for today) edit the component CSS files from within Chrome dev tools with workspaces :(
