I want to enable eclipse specific code completion and syntax highlighting for css to files that ends with gss. The gss files are similar to css files. They are called closure-stylesheets.
Is there a way to configure eclipse that it treats gss files like css files to get code completion enabled?
For individual files you can just right click on the file and select 'Open With > CSS editor' (this will be remembered for future editing)
To set for all files go to 'Preferences > General > Content Types'. Find 'CSS' under 'Text' and click 'Add...' to add a '*.gss' association.
