Intended users: Template Designers, Developer
If you wish to add any custom HTML to the bottom of each page’s head, then this plugin is for you. For example, you can add some custom CSS, a link to an external javascript file or something else.
The problem with editing the template directly is if you ever update the template, your changes will be lost. This plugin works around this issue.
