You can use the Notification Bar to display a custom message above your site. This is a great way to announce a sale, promotion, working hours, or scheduled site maintenance.
The notification Bar can appear on every page of your site or only in specific page.
It can't be customized with text, background color and link.
Make sure you're using Enterprise or Advanced package of Matrix theme.
1. In your admin menu, go to enterprise package and select the widget.
2. Upload to your website the latest js file of Matrix ( at least Matrix-1.8.js ) that can be found in section updates.
3) The last step is to add the code inside the module Widget/HTML.
You add it inside the content of your site to display only in specific page or in footer to make it visible in all pages
The notification bar works fine with all templates with relative position of the header. For Some specific templates, you need to add different section where it will appear, for
example instead of .hs-top-header you add .hs-footer
