Header and Footer Scripts (HFS) module allows you to add style(CSS) and scripts(JS) in your site or, you don’t need to open any file for this purpose. Specially, when you need to add Google Analytics, Heap, Segment or some other Analytics code. By using this plugin all of this can be done from the changes on the Admin Configuration Page. This page comes up with permission. So, by default only admin can make changes in it. But you can also assign the permissions to separated trusted roles.
- You will be able to insert Google Analytics or other Web-analytics code, meta-information, CSS and JS codes easily.
