We'll create fresh WordPress site with Just Headline installed. You have 20 minutes to test the plugin after that site we'll be deleted.
After installation, you will have a new widget available called “Just Headline”.
It can insert the html heading tag h1-h6 into the sidebar or any other widgetized areas (like Page Builders).
Furthermore, you can select a style for it (by default, several pre-defined html tag class names).
You can change available heading sizes and styles with filter hooks. Please check FAQ for more information.
