**Matrix Version:5.4.5.1
We have Design (parse) files which include the deprecated Linked CSS Design Area (since 5.4.4.0).
Using these Design parse files are a number of sub-sites which have their own customisation and within that customisation a reference to a CSS file to add specific styling to that sub-site. All sub-sites also reference a master CSS style sheet included in the Design file.
Question: what is the recommended method of adding custom CSS files to sub-sites with their own customisation without the availability of the now deprecated ‘Linked CSS Design Area’?
Many thanks in advance
Gavin
