I have a custom theme, extends the luma theme, everything works properly.
My custom less modifications were added in web/css/source/_extend.less
Now I would like to create a subtheme from this custom theme I created previously, but if I add a content to /web/css/source/_extend.less
the css modifications added in the parent theme are not taken in consideration.
Shouldn't they be merged or how can i add elegantly new modifications to this new subtheme without copying over again the ones from the previous one. (I understand that _theme.less is not merged but from what I read _extend.less
should be merged)
Can anyone help me?
Thanks
