I have just noticed a peculiar feature:
- developing with Bootstrap scaffold and using LESS source folder (instead of precompiled CSS) no hints are available on Bootstrap classes when one uses HTML file and all the hints are available when one uses PHP file (with HTML structure inside).
- Tested with Bootstrap 2.3.2 and 3.2.0
- BTW, in Netbeans all the Bootstrap classes hints are available with both HTML and PHP extensions. - Tested with 7.4 and 8.0
